Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544192, here are decompositions:
- 3 + 31544189 = 31544192
- 13 + 31544179 = 31544192
- 61 + 31544131 = 31544192
- 103 + 31544089 = 31544192
- 139 + 31544053 = 31544192
- 151 + 31544041 = 31544192
- 181 + 31544011 = 31544192
- 349 + 31543843 = 31544192
Showing the first eight; more decompositions exist.
