Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559744, here are decompositions:

67 + 31559677 = 31559744
103 + 31559641 = 31559744
277 + 31559467 = 31559744
331 + 31559413 = 31559744
373 + 31559371 = 31559744
613 + 31559131 = 31559744
673 + 31559071 = 31559744
751 + 31558993 = 31559744

Showing the first eight; more decompositions exist.
