Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534220, here are decompositions:
- 37 + 31534183 = 31534220
- 79 + 31534141 = 31534220
- 103 + 31534117 = 31534220
- 163 + 31534057 = 31534220
- 241 + 31533979 = 31534220
- 271 + 31533949 = 31534220
- 349 + 31533871 = 31534220
- 373 + 31533847 = 31534220
Showing the first eight; more decompositions exist.
