Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527412, here are decompositions:
- 5 + 31527407 = 31527412
- 23 + 31527389 = 31527412
- 89 + 31527323 = 31527412
- 101 + 31527311 = 31527412
- 179 + 31527233 = 31527412
- 239 + 31527173 = 31527412
- 263 + 31527149 = 31527412
- 269 + 31527143 = 31527412
Showing the first eight; more decompositions exist.
