Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564424, here are decompositions:
- 37 + 31564387 = 31564424
- 97 + 31564327 = 31564424
- 103 + 31564321 = 31564424
- 163 + 31564261 = 31564424
- 181 + 31564243 = 31564424
- 277 + 31564147 = 31564424
- 373 + 31564051 = 31564424
- 457 + 31563967 = 31564424
Showing the first eight; more decompositions exist.
