Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528992, here are decompositions:
- 23 + 31528969 = 31528992
- 83 + 31528909 = 31528992
- 139 + 31528853 = 31528992
- 149 + 31528843 = 31528992
- 151 + 31528841 = 31528992
- 179 + 31528813 = 31528992
- 181 + 31528811 = 31528992
- 191 + 31528801 = 31528992
Showing the first eight; more decompositions exist.
