Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613486, here are decompositions:

103 + 31613383 = 31613486
109 + 31613377 = 31613486
349 + 31613137 = 31613486
367 + 31613119 = 31613486
379 + 31613107 = 31613486
433 + 31613053 = 31613486
547 + 31612939 = 31613486
613 + 31612873 = 31613486

Showing the first eight; more decompositions exist.
