Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527664, here are decompositions:
- 5 + 31527659 = 31527664
- 131 + 31527533 = 31527664
- 167 + 31527497 = 31527664
- 173 + 31527491 = 31527664
- 251 + 31527413 = 31527664
- 257 + 31527407 = 31527664
- 347 + 31527317 = 31527664
- 353 + 31527311 = 31527664
Showing the first eight; more decompositions exist.
