Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538604, here are decompositions:
- 23 + 31538581 = 31538604
- 43 + 31538561 = 31538604
- 47 + 31538557 = 31538604
- 101 + 31538503 = 31538604
- 113 + 31538491 = 31538604
- 127 + 31538477 = 31538604
- 131 + 31538473 = 31538604
- 193 + 31538411 = 31538604
Showing the first eight; more decompositions exist.
