Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452742, here are decompositions:
- 3 + 31452739 = 31452742
- 11 + 31452731 = 31452742
- 23 + 31452719 = 31452742
- 59 + 31452683 = 31452742
- 281 + 31452461 = 31452742
- 401 + 31452341 = 31452742
- 509 + 31452233 = 31452742
- 569 + 31452173 = 31452742
Showing the first eight; more decompositions exist.
