Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523396, here are decompositions:

67 + 31523329 = 31523396
103 + 31523293 = 31523396
277 + 31523119 = 31523396
283 + 31523113 = 31523396
409 + 31522987 = 31523396
523 + 31522873 = 31523396
727 + 31522669 = 31523396
733 + 31522663 = 31523396

Showing the first eight; more decompositions exist.
