Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534320, here are decompositions:
- 19 + 31534301 = 31534320
- 23 + 31534297 = 31534320
- 73 + 31534247 = 31534320
- 79 + 31534241 = 31534320
- 89 + 31534231 = 31534320
- 137 + 31534183 = 31534320
- 151 + 31534169 = 31534320
- 179 + 31534141 = 31534320
Showing the first eight; more decompositions exist.
