Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585616, here are decompositions:
- 3 + 31585613 = 31585616
- 19 + 31585597 = 31585616
- 37 + 31585579 = 31585616
- 67 + 31585549 = 31585616
- 79 + 31585537 = 31585616
- 157 + 31585459 = 31585616
- 163 + 31585453 = 31585616
- 277 + 31585339 = 31585616
Showing the first eight; more decompositions exist.
