Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137812, here are decompositions:
- 41 + 137771 = 137812
- 89 + 137723 = 137812
- 113 + 137699 = 137812
- 173 + 137639 = 137812
- 179 + 137633 = 137812
- 239 + 137573 = 137812
- 293 + 137519 = 137812
- 359 + 137453 = 137812
Showing the first eight; more decompositions exist.
