Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530602, here are decompositions:
- 13 + 31530589 = 31530602
- 31 + 31530571 = 31530602
- 79 + 31530523 = 31530602
- 151 + 31530451 = 31530602
- 193 + 31530409 = 31530602
- 211 + 31530391 = 31530602
- 421 + 31530181 = 31530602
- 541 + 31530061 = 31530602
Showing the first eight; more decompositions exist.
