Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513892, here are decompositions:
- 13 + 31513879 = 31513892
- 19 + 31513873 = 31513892
- 43 + 31513849 = 31513892
- 61 + 31513831 = 31513892
- 73 + 31513819 = 31513892
- 199 + 31513693 = 31513892
- 271 + 31513621 = 31513892
- 313 + 31513579 = 31513892
Showing the first eight; more decompositions exist.
