Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465174, here are decompositions:

113 + 31465061 = 31465174
227 + 31464947 = 31465174
233 + 31464941 = 31465174
347 + 31464827 = 31465174
353 + 31464821 = 31465174
443 + 31464731 = 31465174
557 + 31464617 = 31465174
593 + 31464581 = 31465174

Showing the first eight; more decompositions exist.
