Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541166, here are decompositions:

5 + 31541161 = 31541166
37 + 31541129 = 31541166
53 + 31541113 = 31541166
127 + 31541039 = 31541166
149 + 31541017 = 31541166
227 + 31540939 = 31541166
353 + 31540813 = 31541166
379 + 31540787 = 31541166

Showing the first eight; more decompositions exist.
