Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528578, here are decompositions:

5 + 31528573 = 31528578
19 + 31528559 = 31528578
31 + 31528547 = 31528578
47 + 31528531 = 31528578
79 + 31528499 = 31528578
127 + 31528451 = 31528578
131 + 31528447 = 31528578
229 + 31528349 = 31528578

Showing the first eight; more decompositions exist.
