Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529074, here are decompositions:
- 107 + 31528967 = 31529074
- 233 + 31528841 = 31529074
- 251 + 31528823 = 31529074
- 263 + 31528811 = 31529074
- 461 + 31528613 = 31529074
- 641 + 31528433 = 31529074
- 701 + 31528373 = 31529074
- 761 + 31528313 = 31529074
Showing the first eight; more decompositions exist.
