Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531184, here are decompositions:
- 67 + 31531117 = 31531184
- 127 + 31531057 = 31531184
- 211 + 31530973 = 31531184
- 241 + 31530943 = 31531184
- 283 + 31530901 = 31531184
- 523 + 31530661 = 31531184
- 541 + 31530643 = 31531184
- 547 + 31530637 = 31531184
Showing the first eight; more decompositions exist.
