Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528746, here are decompositions:

5 + 31528741 = 31528746
17 + 31528729 = 31528746
23 + 31528723 = 31528746
113 + 31528633 = 31528746
167 + 31528579 = 31528746
173 + 31528573 = 31528746
199 + 31528547 = 31528746
313 + 31528433 = 31528746

Showing the first eight; more decompositions exist.
