Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537182, here are decompositions:
- 29 + 31537153 = 31537182
- 31 + 31537151 = 31537182
- 139 + 31537043 = 31537182
- 179 + 31537003 = 31537182
- 181 + 31537001 = 31537182
- 191 + 31536991 = 31537182
- 199 + 31536983 = 31537182
- 223 + 31536959 = 31537182
Showing the first eight; more decompositions exist.
