Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528608, here are decompositions:
- 29 + 31528579 = 31528608
- 61 + 31528547 = 31528608
- 107 + 31528501 = 31528608
- 109 + 31528499 = 31528608
- 149 + 31528459 = 31528608
- 157 + 31528451 = 31528608
- 271 + 31528337 = 31528608
- 281 + 31528327 = 31528608
Showing the first eight; more decompositions exist.
