Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544912, here are decompositions:
- 13 + 31544899 = 31544912
- 163 + 31544749 = 31544912
- 193 + 31544719 = 31544912
- 199 + 31544713 = 31544912
- 379 + 31544533 = 31544912
- 541 + 31544371 = 31544912
- 601 + 31544311 = 31544912
- 631 + 31544281 = 31544912
Showing the first eight; more decompositions exist.
