Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541328, here are decompositions:
- 31 + 31541297 = 31541328
- 47 + 31541281 = 31541328
- 59 + 31541269 = 31541328
- 61 + 31541267 = 31541328
- 149 + 31541179 = 31541328
- 167 + 31541161 = 31541328
- 199 + 31541129 = 31541328
- 211 + 31541117 = 31541328
Showing the first eight; more decompositions exist.
