Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615800, here are decompositions:
- 17 + 31615783 = 31615800
- 37 + 31615763 = 31615800
- 43 + 31615757 = 31615800
- 59 + 31615741 = 31615800
- 71 + 31615729 = 31615800
- 89 + 31615711 = 31615800
- 131 + 31615669 = 31615800
- 137 + 31615663 = 31615800
Showing the first eight; more decompositions exist.
