Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528994, here are decompositions:
- 151 + 31528843 = 31528994
- 163 + 31528831 = 31528994
- 181 + 31528813 = 31528994
- 193 + 31528801 = 31528994
- 271 + 31528723 = 31528994
- 373 + 31528621 = 31528994
- 421 + 31528573 = 31528994
- 463 + 31528531 = 31528994
Showing the first eight; more decompositions exist.
