Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137786, here are decompositions:
- 43 + 137743 = 137786
- 73 + 137713 = 137786
- 79 + 137707 = 137786
- 127 + 137659 = 137786
- 163 + 137623 = 137786
- 193 + 137593 = 137786
- 199 + 137587 = 137786
- 349 + 137437 = 137786
Showing the first eight; more decompositions exist.
