Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486200, here are decompositions:
- 37 + 31486163 = 31486200
- 71 + 31486129 = 31486200
- 79 + 31486121 = 31486200
- 113 + 31486087 = 31486200
- 167 + 31486033 = 31486200
- 191 + 31486009 = 31486200
- 227 + 31485973 = 31486200
- 241 + 31485959 = 31486200
Showing the first eight; more decompositions exist.
