Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508054, here are decompositions:

37 + 31508017 = 31508054
73 + 31507981 = 31508054
103 + 31507951 = 31508054
157 + 31507897 = 31508054
283 + 31507771 = 31508054
421 + 31507633 = 31508054
463 + 31507591 = 31508054
547 + 31507507 = 31508054

Showing the first eight; more decompositions exist.
