Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504634, here are decompositions:

43 + 31504591 = 31504634
61 + 31504573 = 31504634
67 + 31504567 = 31504634
181 + 31504453 = 31504634
277 + 31504357 = 31504634
283 + 31504351 = 31504634
307 + 31504327 = 31504634
331 + 31504303 = 31504634

Showing the first eight; more decompositions exist.
