Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564370, here are decompositions:
- 37 + 31564333 = 31564370
- 43 + 31564327 = 31564370
- 109 + 31564261 = 31564370
- 127 + 31564243 = 31564370
- 163 + 31564207 = 31564370
- 199 + 31564171 = 31564370
- 223 + 31564147 = 31564370
- 241 + 31564129 = 31564370
Showing the first eight; more decompositions exist.
