Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544918, here are decompositions:
- 19 + 31544899 = 31544918
- 61 + 31544857 = 31544918
- 199 + 31544719 = 31544918
- 331 + 31544587 = 31544918
- 367 + 31544551 = 31544918
- 409 + 31544509 = 31544918
- 547 + 31544371 = 31544918
- 571 + 31544347 = 31544918
Showing the first eight; more decompositions exist.
