Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600140, here are decompositions:
- 7 + 31600133 = 31600140
- 23 + 31600117 = 31600140
- 37 + 31600103 = 31600140
- 41 + 31600099 = 31600140
- 53 + 31600087 = 31600140
- 79 + 31600061 = 31600140
- 83 + 31600057 = 31600140
- 97 + 31600043 = 31600140
Showing the first eight; more decompositions exist.
