Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540176, here are decompositions:

13 + 31540163 = 31540176
29 + 31540147 = 31540176
53 + 31540123 = 31540176
67 + 31540109 = 31540176
113 + 31540063 = 31540176
163 + 31540013 = 31540176
167 + 31540009 = 31540176
313 + 31539863 = 31540176

Showing the first eight; more decompositions exist.
