Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613752, here are decompositions:

83 + 31613669 = 31613752
113 + 31613639 = 31613752
173 + 31613579 = 31613752
239 + 31613513 = 31613752
311 + 31613441 = 31613752
353 + 31613399 = 31613752
419 + 31613333 = 31613752
461 + 31613291 = 31613752

Showing the first eight; more decompositions exist.
