Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529752, here are decompositions:
- 3 + 31529749 = 31529752
- 71 + 31529681 = 31529752
- 83 + 31529669 = 31529752
- 101 + 31529651 = 31529752
- 281 + 31529471 = 31529752
- 431 + 31529321 = 31529752
- 479 + 31529273 = 31529752
- 503 + 31529249 = 31529752
Showing the first eight; more decompositions exist.
