Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1662, here are decompositions:
- 5 + 1657 = 1662
- 41 + 1621 = 1662
- 43 + 1619 = 1662
- 53 + 1609 = 1662
- 61 + 1601 = 1662
- 79 + 1583 = 1662
- 83 + 1579 = 1662
- 103 + 1559 = 1662
Showing the first eight; more decompositions exist.

The digit sequence 1662 first appears in π at position 22,067 of the decimal expansion (the 22,067ordinal-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.
