Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504584, here are decompositions:

11 + 31504573 = 31504584
17 + 31504567 = 31504584
37 + 31504547 = 31504584
103 + 31504481 = 31504584
131 + 31504453 = 31504584
197 + 31504387 = 31504584
211 + 31504373 = 31504584
227 + 31504357 = 31504584

Showing the first eight; more decompositions exist.
