Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606784, here are decompositions:
- 31 + 31606753 = 31606784
- 43 + 31606741 = 31606784
- 73 + 31606711 = 31606784
- 103 + 31606681 = 31606784
- 127 + 31606657 = 31606784
- 241 + 31606543 = 31606784
- 373 + 31606411 = 31606784
- 397 + 31606387 = 31606784
Showing the first eight; more decompositions exist.
