Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529560, here are decompositions:
- 3 + 31529557 = 31529560
- 53 + 31529507 = 31529560
- 89 + 31529471 = 31529560
- 113 + 31529447 = 31529560
- 239 + 31529321 = 31529560
- 281 + 31529279 = 31529560
- 311 + 31529249 = 31529560
- 317 + 31529243 = 31529560
Showing the first eight; more decompositions exist.
