Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472114, here are decompositions:

7 + 31472107 = 31472114
61 + 31472053 = 31472114
73 + 31472041 = 31472114
103 + 31472011 = 31472114
181 + 31471933 = 31472114
283 + 31471831 = 31472114
433 + 31471681 = 31472114
523 + 31471591 = 31472114

Showing the first eight; more decompositions exist.
