Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529090, here are decompositions:
- 3 + 31529087 = 31529090
- 37 + 31529053 = 31529090
- 97 + 31528993 = 31529090
- 181 + 31528909 = 31529090
- 277 + 31528813 = 31529090
- 283 + 31528807 = 31529090
- 349 + 31528741 = 31529090
- 367 + 31528723 = 31529090
Showing the first eight; more decompositions exist.
