Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544286, here are decompositions:
- 5 + 31544281 = 31544286
- 73 + 31544213 = 31544286
- 79 + 31544207 = 31544286
- 97 + 31544189 = 31544286
- 107 + 31544179 = 31544286
- 197 + 31544089 = 31544286
- 229 + 31544057 = 31544286
- 233 + 31544053 = 31544286
Showing the first eight; more decompositions exist.
