Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504934, here are decompositions:

31 + 31504903 = 31504934
61 + 31504873 = 31504934
151 + 31504783 = 31504934
283 + 31504651 = 31504934
367 + 31504567 = 31504934
547 + 31504387 = 31504934
577 + 31504357 = 31504934
607 + 31504327 = 31504934

Showing the first eight; more decompositions exist.
