Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529536, here are decompositions:
- 29 + 31529507 = 31529536
- 89 + 31529447 = 31529536
- 257 + 31529279 = 31529536
- 263 + 31529273 = 31529536
- 293 + 31529243 = 31529536
- 317 + 31529219 = 31529536
- 449 + 31529087 = 31529536
- 569 + 31528967 = 31529536
Showing the first eight; more decompositions exist.
