Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534194, here are decompositions:
- 7 + 31534187 = 31534194
- 11 + 31534183 = 31534194
- 53 + 31534141 = 31534194
- 73 + 31534121 = 31534194
- 127 + 31534067 = 31534194
- 137 + 31534057 = 31534194
- 227 + 31533967 = 31534194
- 271 + 31533923 = 31534194
Showing the first eight; more decompositions exist.
