Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544240, here are decompositions:
- 19 + 31544221 = 31544240
- 61 + 31544179 = 31544240
- 73 + 31544167 = 31544240
- 109 + 31544131 = 31544240
- 151 + 31544089 = 31544240
- 163 + 31544077 = 31544240
- 199 + 31544041 = 31544240
- 229 + 31544011 = 31544240
Showing the first eight; more decompositions exist.
