Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 128334, here are decompositions:
- 7 + 128327 = 128334
- 13 + 128321 = 128334
- 23 + 128311 = 128334
- 43 + 128291 = 128334
- 47 + 128287 = 128334
- 61 + 128273 = 128334
- 97 + 128237 = 128334
- 113 + 128221 = 128334
Showing the first eight; more decompositions exist.
