Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462066, here are decompositions:

59 + 31462007 = 31462066
89 + 31461977 = 31462066
173 + 31461893 = 31462066
179 + 31461887 = 31462066
509 + 31461557 = 31462066
653 + 31461413 = 31462066
773 + 31461293 = 31462066
887 + 31461179 = 31462066

Showing the first eight; more decompositions exist.
