Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470, here are decompositions:
- 73 + 31397 = 31470
- 79 + 31391 = 31470
- 83 + 31387 = 31470
- 113 + 31357 = 31470
- 137 + 31333 = 31470
- 149 + 31321 = 31470
- 151 + 31319 = 31470
- 163 + 31307 = 31470
Showing the first eight; more decompositions exist.
