Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540150, here are decompositions:

3 + 31540147 = 31540150
41 + 31540109 = 31540150
137 + 31540013 = 31540150
179 + 31539971 = 31540150
293 + 31539857 = 31540150
311 + 31539839 = 31540150
443 + 31539707 = 31540150
479 + 31539671 = 31540150

Showing the first eight; more decompositions exist.
