Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603084, here are decompositions:

5 + 31603079 = 31603084
11 + 31603073 = 31603084
167 + 31602917 = 31603084
281 + 31602803 = 31603084
503 + 31602581 = 31603084
563 + 31602521 = 31603084
587 + 31602497 = 31603084
641 + 31602443 = 31603084

Showing the first eight; more decompositions exist.
