Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541188, here are decompositions:
- 47 + 31541141 = 31541188
- 59 + 31541129 = 31541188
- 71 + 31541117 = 31541188
- 137 + 31541051 = 31541188
- 149 + 31541039 = 31541188
- 167 + 31541021 = 31541188
- 197 + 31540991 = 31541188
- 227 + 31540961 = 31541188
Showing the first eight; more decompositions exist.
