Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541146, here are decompositions:

5 + 31541141 = 31541146
17 + 31541129 = 31541146
29 + 31541117 = 31541146
107 + 31541039 = 31541146
167 + 31540979 = 31541146
359 + 31540787 = 31541146
419 + 31540727 = 31541146
467 + 31540679 = 31541146

Showing the first eight; more decompositions exist.
