Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466158, here are decompositions:

107 + 31466051 = 31466158
179 + 31465979 = 31466158
401 + 31465757 = 31466158
431 + 31465727 = 31466158
461 + 31465697 = 31466158
509 + 31465649 = 31466158
557 + 31465601 = 31466158
587 + 31465571 = 31466158

Showing the first eight; more decompositions exist.
