Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1784, here are decompositions:
- 7 + 1777 = 1784
- 31 + 1753 = 1784
- 37 + 1747 = 1784
- 43 + 1741 = 1784
- 61 + 1723 = 1784
- 127 + 1657 = 1784
- 157 + 1627 = 1784
- 163 + 1621 = 1784
Showing the first eight; more decompositions exist.

The digit sequence 1784 first appears in π at position 6,291 of the decimal expansion (the 6,291ordinal-suffix:st 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.
