Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544202, here are decompositions:
- 13 + 31544189 = 31544202
- 23 + 31544179 = 31544202
- 31 + 31544171 = 31544202
- 71 + 31544131 = 31544202
- 103 + 31544099 = 31544202
- 113 + 31544089 = 31544202
- 149 + 31544053 = 31544202
- 163 + 31544039 = 31544202
Showing the first eight; more decompositions exist.
