Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527574, here are decompositions:
- 5 + 31527569 = 31527574
- 41 + 31527533 = 31527574
- 53 + 31527521 = 31527574
- 83 + 31527491 = 31527574
- 167 + 31527407 = 31527574
- 251 + 31527323 = 31527574
- 257 + 31527317 = 31527574
- 263 + 31527311 = 31527574
Showing the first eight; more decompositions exist.
