Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544780, here are decompositions:
- 31 + 31544749 = 31544780
- 61 + 31544719 = 31544780
- 67 + 31544713 = 31544780
- 193 + 31544587 = 31544780
- 229 + 31544551 = 31544780
- 271 + 31544509 = 31544780
- 409 + 31544371 = 31544780
- 433 + 31544347 = 31544780
Showing the first eight; more decompositions exist.
