Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466200, here are decompositions:

137 + 31466063 = 31466200
149 + 31466051 = 31466200
197 + 31466003 = 31466200
419 + 31465781 = 31466200
443 + 31465757 = 31466200
503 + 31465697 = 31466200
569 + 31465631 = 31466200
599 + 31465601 = 31466200

Showing the first eight; more decompositions exist.
