Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528730, here are decompositions:

7 + 31528723 = 31528730
61 + 31528669 = 31528730
97 + 31528633 = 31528730
109 + 31528621 = 31528730
151 + 31528579 = 31528730
157 + 31528573 = 31528730
199 + 31528531 = 31528730
229 + 31528501 = 31528730

Showing the first eight; more decompositions exist.
