Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137458, here are decompositions:
- 5 + 137453 = 137458
- 11 + 137447 = 137458
- 59 + 137399 = 137458
- 71 + 137387 = 137458
- 89 + 137369 = 137458
- 137 + 137321 = 137458
- 179 + 137279 = 137458
- 239 + 137219 = 137458
Showing the first eight; more decompositions exist.
