Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553936, here are decompositions:

103 + 31553833 = 31553936
229 + 31553707 = 31553936
277 + 31553659 = 31553936
409 + 31553527 = 31553936
433 + 31553503 = 31553936
577 + 31553359 = 31553936
859 + 31553077 = 31553936
919 + 31553017 = 31553936

Showing the first eight; more decompositions exist.
