Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619016, here are decompositions:
- 7 + 31619009 = 31619016
- 17 + 31618999 = 31619016
- 67 + 31618949 = 31619016
- 73 + 31618943 = 31619016
- 137 + 31618879 = 31619016
- 167 + 31618849 = 31619016
- 193 + 31618823 = 31619016
- 197 + 31618819 = 31619016
Showing the first eight; more decompositions exist.
