Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538710, here are decompositions:
- 17 + 31538693 = 31538710
- 131 + 31538579 = 31538710
- 149 + 31538561 = 31538710
- 233 + 31538477 = 31538710
- 383 + 31538327 = 31538710
- 449 + 31538261 = 31538710
- 503 + 31538207 = 31538710
- 557 + 31538153 = 31538710
Showing the first eight; more decompositions exist.
