Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538592, here are decompositions:
- 11 + 31538581 = 31538592
- 13 + 31538579 = 31538592
- 23 + 31538569 = 31538592
- 31 + 31538561 = 31538592
- 53 + 31538539 = 31538592
- 89 + 31538503 = 31538592
- 101 + 31538491 = 31538592
- 103 + 31538489 = 31538592
Showing the first eight; more decompositions exist.
