Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627522, here are decompositions:

11 + 31627511 = 31627522
131 + 31627391 = 31627522
149 + 31627373 = 31627522
233 + 31627289 = 31627522
389 + 31627133 = 31627522
401 + 31627121 = 31627522
431 + 31627091 = 31627522
449 + 31627073 = 31627522

Showing the first eight; more decompositions exist.
