Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529212, here are decompositions:
- 131 + 31529081 = 31529212
- 359 + 31528853 = 31529212
- 389 + 31528823 = 31529212
- 401 + 31528811 = 31529212
- 461 + 31528751 = 31529212
- 599 + 31528613 = 31529212
- 653 + 31528559 = 31529212
- 761 + 31528451 = 31529212
Showing the first eight; more decompositions exist.
