Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528462, here are decompositions:
- 3 + 31528459 = 31528462
- 11 + 31528451 = 31528462
- 29 + 31528433 = 31528462
- 89 + 31528373 = 31528462
- 113 + 31528349 = 31528462
- 149 + 31528313 = 31528462
- 179 + 31528283 = 31528462
- 233 + 31528229 = 31528462
Showing the first eight; more decompositions exist.
