Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504744, here are decompositions:

41 + 31504703 = 31504744
53 + 31504691 = 31504744
83 + 31504661 = 31504744
137 + 31504607 = 31504744
197 + 31504547 = 31504744
251 + 31504493 = 31504744
263 + 31504481 = 31504744
617 + 31504127 = 31504744

Showing the first eight; more decompositions exist.
