Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466250, here are decompositions:

17 + 31466233 = 31466250
29 + 31466221 = 31466250
43 + 31466207 = 31466250
107 + 31466143 = 31466250
113 + 31466137 = 31466250
131 + 31466119 = 31466250
149 + 31466101 = 31466250
197 + 31466053 = 31466250

Showing the first eight; more decompositions exist.
