Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485506, here are decompositions:
- 79 + 31485427 = 31485506
- 109 + 31485397 = 31485506
- 127 + 31485379 = 31485506
- 193 + 31485313 = 31485506
- 223 + 31485283 = 31485506
- 229 + 31485277 = 31485506
- 313 + 31485193 = 31485506
- 439 + 31485067 = 31485506
Showing the first eight; more decompositions exist.
