Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627400, here are decompositions:
- 43 + 31627357 = 31627400
- 67 + 31627333 = 31627400
- 97 + 31627303 = 31627400
- 139 + 31627261 = 31627400
- 151 + 31627249 = 31627400
- 157 + 31627243 = 31627400
- 163 + 31627237 = 31627400
- 199 + 31627201 = 31627400
Showing the first eight; more decompositions exist.
