Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504924, here are decompositions:

41 + 31504883 = 31504924
233 + 31504691 = 31504924
257 + 31504667 = 31504924
263 + 31504661 = 31504924
317 + 31504607 = 31504924
431 + 31504493 = 31504924
443 + 31504481 = 31504924
557 + 31504367 = 31504924

Showing the first eight; more decompositions exist.
