Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31621190, here are decompositions:
- 67 + 31621123 = 31621190
- 109 + 31621081 = 31621190
- 127 + 31621063 = 31621190
- 157 + 31621033 = 31621190
- 163 + 31621027 = 31621190
- 397 + 31620793 = 31621190
- 439 + 31620751 = 31621190
- 457 + 31620733 = 31621190
Showing the first eight; more decompositions exist.
