Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612200, here are decompositions:
- 79 + 31612121 = 31612200
- 131 + 31612069 = 31612200
- 157 + 31612043 = 31612200
- 283 + 31611917 = 31612200
- 293 + 31611907 = 31612200
- 307 + 31611893 = 31612200
- 317 + 31611883 = 31612200
- 331 + 31611869 = 31612200
Showing the first eight; more decompositions exist.
