Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529338, here are decompositions:
- 17 + 31529321 = 31529338
- 59 + 31529279 = 31529338
- 89 + 31529249 = 31529338
- 251 + 31529087 = 31529338
- 257 + 31529081 = 31529338
- 587 + 31528751 = 31529338
- 641 + 31528697 = 31529338
- 839 + 31528499 = 31529338
Showing the first eight; more decompositions exist.
