Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514996, here are decompositions:

103 + 31514893 = 31514996
127 + 31514869 = 31514996
157 + 31514839 = 31514996
307 + 31514689 = 31514996
367 + 31514629 = 31514996
397 + 31514599 = 31514996
463 + 31514533 = 31514996
523 + 31514473 = 31514996

Showing the first eight; more decompositions exist.
