Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528892, here are decompositions:

61 + 31528831 = 31528892
79 + 31528813 = 31528892
151 + 31528741 = 31528892
163 + 31528729 = 31528892
223 + 31528669 = 31528892
271 + 31528621 = 31528892
313 + 31528579 = 31528892
433 + 31528459 = 31528892

Showing the first eight; more decompositions exist.
