Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466170, here are decompositions:

107 + 31466063 = 31466170
167 + 31466003 = 31466170
191 + 31465979 = 31466170
389 + 31465781 = 31466170
443 + 31465727 = 31466170
509 + 31465661 = 31466170
521 + 31465649 = 31466170
569 + 31465601 = 31466170

Showing the first eight; more decompositions exist.
