Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535744, here are decompositions:
- 3 + 31535741 = 31535744
- 73 + 31535671 = 31535744
- 151 + 31535593 = 31535744
- 193 + 31535551 = 31535744
- 241 + 31535503 = 31535744
- 277 + 31535467 = 31535744
- 367 + 31535377 = 31535744
- 433 + 31535311 = 31535744
Showing the first eight; more decompositions exist.
