Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504936, here are decompositions:

53 + 31504883 = 31504936
137 + 31504799 = 31504936
233 + 31504703 = 31504936
269 + 31504667 = 31504936
317 + 31504619 = 31504936
389 + 31504547 = 31504936
443 + 31504493 = 31504936
563 + 31504373 = 31504936

Showing the first eight; more decompositions exist.
