Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137750, here are decompositions:
- 7 + 137743 = 137750
- 13 + 137737 = 137750
- 37 + 137713 = 137750
- 43 + 137707 = 137750
- 97 + 137653 = 137750
- 127 + 137623 = 137750
- 157 + 137593 = 137750
- 163 + 137587 = 137750
Showing the first eight; more decompositions exist.
