Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543504, here are decompositions:

23 + 31543481 = 31543504
53 + 31543451 = 31543504
107 + 31543397 = 31543504
173 + 31543331 = 31543504
281 + 31543223 = 31543504
401 + 31543103 = 31543504
563 + 31542941 = 31543504
593 + 31542911 = 31543504

Showing the first eight; more decompositions exist.
