Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527504, here are decompositions:
- 5 + 31527499 = 31527504
- 7 + 31527497 = 31527504
- 13 + 31527491 = 31527504
- 23 + 31527481 = 31527504
- 97 + 31527407 = 31527504
- 181 + 31527323 = 31527504
- 193 + 31527311 = 31527504
- 227 + 31527277 = 31527504
Showing the first eight; more decompositions exist.
