Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514804, here are decompositions:

73 + 31514731 = 31514804
151 + 31514653 = 31514804
163 + 31514641 = 31514804
271 + 31514533 = 31514804
331 + 31514473 = 31514804
613 + 31514191 = 31514804
661 + 31514143 = 31514804
691 + 31514113 = 31514804

Showing the first eight; more decompositions exist.
