Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537650, here are decompositions:
- 19 + 31537631 = 31537650
- 41 + 31537609 = 31537650
- 47 + 31537603 = 31537650
- 59 + 31537591 = 31537650
- 103 + 31537547 = 31537650
- 107 + 31537543 = 31537650
- 173 + 31537477 = 31537650
- 181 + 31537469 = 31537650
Showing the first eight; more decompositions exist.
