Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528046, here are decompositions:

79 + 31527967 = 31528046
229 + 31527817 = 31528046
337 + 31527709 = 31528046
349 + 31527697 = 31528046
463 + 31527583 = 31528046
523 + 31527523 = 31528046
547 + 31527499 = 31528046
769 + 31527277 = 31528046

Showing the first eight; more decompositions exist.
