Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544786, here are decompositions:
- 3 + 31544783 = 31544786
- 37 + 31544749 = 31544786
- 67 + 31544719 = 31544786
- 73 + 31544713 = 31544786
- 199 + 31544587 = 31544786
- 277 + 31544509 = 31544786
- 439 + 31544347 = 31544786
- 463 + 31544323 = 31544786
Showing the first eight; more decompositions exist.
