Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552916, here are decompositions:

37 + 31552879 = 31552916
223 + 31552693 = 31552916
277 + 31552639 = 31552916
313 + 31552603 = 31552916
337 + 31552579 = 31552916
379 + 31552537 = 31552916
487 + 31552429 = 31552916
523 + 31552393 = 31552916

Showing the first eight; more decompositions exist.
