Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496784, here are decompositions:
- 5 + 31496779 = 31496784
- 43 + 31496741 = 31496784
- 107 + 31496677 = 31496784
- 113 + 31496671 = 31496784
- 173 + 31496611 = 31496784
- 191 + 31496593 = 31496784
- 197 + 31496587 = 31496784
- 211 + 31496573 = 31496784
Showing the first eight; more decompositions exist.
