Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528476, here are decompositions:
- 17 + 31528459 = 31528476
- 29 + 31528447 = 31528476
- 43 + 31528433 = 31528476
- 103 + 31528373 = 31528476
- 113 + 31528363 = 31528476
- 127 + 31528349 = 31528476
- 139 + 31528337 = 31528476
- 149 + 31528327 = 31528476
Showing the first eight; more decompositions exist.
