Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547802, here are decompositions:
- 19 + 31547783 = 31547802
- 53 + 31547749 = 31547802
- 71 + 31547731 = 31547802
- 101 + 31547701 = 31547802
- 109 + 31547693 = 31547802
- 131 + 31547671 = 31547802
- 173 + 31547629 = 31547802
- 193 + 31547609 = 31547802
Showing the first eight; more decompositions exist.
