Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 128374, here are decompositions:
- 23 + 128351 = 128374
- 47 + 128327 = 128374
- 53 + 128321 = 128374
- 83 + 128291 = 128374
- 101 + 128273 = 128374
- 137 + 128237 = 128374
- 173 + 128201 = 128374
- 227 + 128147 = 128374
Showing the first eight; more decompositions exist.
