Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527550, here are decompositions:
- 17 + 31527533 = 31527550
- 29 + 31527521 = 31527550
- 53 + 31527497 = 31527550
- 59 + 31527491 = 31527550
- 137 + 31527413 = 31527550
- 227 + 31527323 = 31527550
- 233 + 31527317 = 31527550
- 239 + 31527311 = 31527550
Showing the first eight; more decompositions exist.
