Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544282, here are decompositions:
- 61 + 31544221 = 31544282
- 103 + 31544179 = 31544282
- 151 + 31544131 = 31544282
- 193 + 31544089 = 31544282
- 229 + 31544053 = 31544282
- 241 + 31544041 = 31544282
- 271 + 31544011 = 31544282
- 379 + 31543903 = 31544282
Showing the first eight; more decompositions exist.
