Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504600, here are decompositions:

53 + 31504547 = 31504600
107 + 31504493 = 31504600
227 + 31504373 = 31504600
233 + 31504367 = 31504600
467 + 31504133 = 31504600
503 + 31504097 = 31504600
563 + 31504037 = 31504600
587 + 31504013 = 31504600

Showing the first eight; more decompositions exist.
