Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538364, here are decompositions:
- 31 + 31538333 = 31538364
- 37 + 31538327 = 31538364
- 103 + 31538261 = 31538364
- 113 + 31538251 = 31538364
- 157 + 31538207 = 31538364
- 211 + 31538153 = 31538364
- 223 + 31538141 = 31538364
- 227 + 31538137 = 31538364
Showing the first eight; more decompositions exist.
