Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544184, here are decompositions:
- 5 + 31544179 = 31544184
- 13 + 31544171 = 31544184
- 17 + 31544167 = 31544184
- 31 + 31544153 = 31544184
- 53 + 31544131 = 31544184
- 107 + 31544077 = 31544184
- 127 + 31544057 = 31544184
- 131 + 31544053 = 31544184
Showing the first eight; more decompositions exist.
