Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539284, here are decompositions:
- 13 + 31539271 = 31539284
- 43 + 31539241 = 31539284
- 211 + 31539073 = 31539284
- 223 + 31539061 = 31539284
- 241 + 31539043 = 31539284
- 277 + 31539007 = 31539284
- 397 + 31538887 = 31539284
- 457 + 31538827 = 31539284
Showing the first eight; more decompositions exist.
