Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552456, here are decompositions:

53 + 31552403 = 31552456
227 + 31552229 = 31552456
263 + 31552193 = 31552456
317 + 31552139 = 31552456
479 + 31551977 = 31552456
599 + 31551857 = 31552456
653 + 31551803 = 31552456
773 + 31551683 = 31552456

Showing the first eight; more decompositions exist.
