Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540122, here are decompositions:

13 + 31540109 = 31540122
23 + 31540099 = 31540122
59 + 31540063 = 31540122
109 + 31540013 = 31540122
113 + 31540009 = 31540122
151 + 31539971 = 31540122
191 + 31539931 = 31540122
233 + 31539889 = 31540122

Showing the first eight; more decompositions exist.
