Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529890, here are decompositions:
- 47 + 31529843 = 31529890
- 71 + 31529819 = 31529890
- 107 + 31529783 = 31529890
- 173 + 31529717 = 31529890
- 239 + 31529651 = 31529890
- 383 + 31529507 = 31529890
- 419 + 31529471 = 31529890
- 443 + 31529447 = 31529890
Showing the first eight; more decompositions exist.
