Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539046, here are decompositions:
- 3 + 31539043 = 31539046
- 59 + 31538987 = 31539046
- 239 + 31538807 = 31539046
- 257 + 31538789 = 31539046
- 293 + 31538753 = 31539046
- 317 + 31538729 = 31539046
- 353 + 31538693 = 31539046
- 467 + 31538579 = 31539046
Showing the first eight; more decompositions exist.
