Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627454, here are decompositions:

43 + 31627411 = 31627454
97 + 31627357 = 31627454
151 + 31627303 = 31627454
193 + 31627261 = 31627454
211 + 31627243 = 31627454
421 + 31627033 = 31627454
487 + 31626967 = 31627454
571 + 31626883 = 31627454

Showing the first eight; more decompositions exist.
