Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9998, here are decompositions:
- 31 + 9967 = 9998
- 67 + 9931 = 9998
- 97 + 9901 = 9998
- 127 + 9871 = 9998
- 139 + 9859 = 9998
- 181 + 9817 = 9998
- 211 + 9787 = 9998
- 229 + 9769 = 9998
Showing the first eight; more decompositions exist.

The digit sequence 9998 first appears in π at position 765 of the decimal expansion (the 765ordinal-suffix:th digit after the integer 3).
Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
