Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564184, here are decompositions:
- 13 + 31564171 = 31564184
- 37 + 31564147 = 31564184
- 241 + 31563943 = 31564184
- 277 + 31563907 = 31564184
- 307 + 31563877 = 31564184
- 313 + 31563871 = 31564184
- 367 + 31563817 = 31564184
- 397 + 31563787 = 31564184
Showing the first eight; more decompositions exist.
