Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538502, here are decompositions:

11 + 31538491 = 31538502
13 + 31538489 = 31538502
29 + 31538473 = 31538502
53 + 31538449 = 31538502
59 + 31538443 = 31538502
131 + 31538371 = 31538502
173 + 31538329 = 31538502
241 + 31538261 = 31538502

Showing the first eight; more decompositions exist.
