Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530062, here are decompositions:

19 + 31530043 = 31530062
61 + 31530001 = 31530062
139 + 31529923 = 31530062
163 + 31529899 = 31530062
181 + 31529881 = 31530062
313 + 31529749 = 31530062
433 + 31529629 = 31530062
439 + 31529623 = 31530062

Showing the first eight; more decompositions exist.
