Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627328, here are decompositions:

67 + 31627261 = 31627328
79 + 31627249 = 31627328
127 + 31627201 = 31627328
277 + 31627051 = 31627328
349 + 31626979 = 31627328
487 + 31626841 = 31627328
541 + 31626787 = 31627328
619 + 31626709 = 31627328

Showing the first eight; more decompositions exist.
