Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514174, here are decompositions:

31 + 31514143 = 31514174
61 + 31514113 = 31514174
73 + 31514101 = 31514174
151 + 31514023 = 31514174
283 + 31513891 = 31514174
331 + 31513843 = 31514174
613 + 31513561 = 31514174
751 + 31513423 = 31514174

Showing the first eight; more decompositions exist.
