Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541232, here are decompositions:
- 53 + 31541179 = 31541232
- 59 + 31541173 = 31541232
- 71 + 31541161 = 31541232
- 103 + 31541129 = 31541232
- 131 + 31541101 = 31541232
- 181 + 31541051 = 31541232
- 193 + 31541039 = 31541232
- 211 + 31541021 = 31541232
Showing the first eight; more decompositions exist.
