Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529046, here are decompositions:
- 53 + 31528993 = 31529046
- 79 + 31528967 = 31529046
- 137 + 31528909 = 31529046
- 193 + 31528853 = 31529046
- 223 + 31528823 = 31529046
- 233 + 31528813 = 31529046
- 239 + 31528807 = 31529046
- 317 + 31528729 = 31529046
Showing the first eight; more decompositions exist.
