Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508552, here are decompositions:
- 3 + 31508549 = 31508552
- 43 + 31508509 = 31508552
- 109 + 31508443 = 31508552
- 193 + 31508359 = 31508552
- 223 + 31508329 = 31508552
- 241 + 31508311 = 31508552
- 349 + 31508203 = 31508552
- 373 + 31508179 = 31508552
Showing the first eight; more decompositions exist.
