Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31572164, here are decompositions:
- 3 + 31572161 = 31572164
- 7 + 31572157 = 31572164
- 31 + 31572133 = 31572164
- 157 + 31572007 = 31572164
- 181 + 31571983 = 31572164
- 277 + 31571887 = 31572164
- 331 + 31571833 = 31572164
- 433 + 31571731 = 31572164
Showing the first eight; more decompositions exist.
