Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544562, here are decompositions:

11 + 31544551 = 31544562
19 + 31544543 = 31544562
29 + 31544533 = 31544562
31 + 31544531 = 31544562
53 + 31544509 = 31544562
191 + 31544371 = 31544562
199 + 31544363 = 31544562
239 + 31544323 = 31544562

Showing the first eight; more decompositions exist.
