Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615934, here are decompositions:
- 13 + 31615921 = 31615934
- 43 + 31615891 = 31615934
- 127 + 31615807 = 31615934
- 151 + 31615783 = 31615934
- 193 + 31615741 = 31615934
- 223 + 31615711 = 31615934
- 271 + 31615663 = 31615934
- 283 + 31615651 = 31615934
Showing the first eight; more decompositions exist.
