Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529030, here are decompositions:

37 + 31528993 = 31529030
61 + 31528969 = 31529030
199 + 31528831 = 31529030
223 + 31528807 = 31529030
229 + 31528801 = 31529030
307 + 31528723 = 31529030
397 + 31528633 = 31529030
409 + 31528621 = 31529030

Showing the first eight; more decompositions exist.
