Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552192, here are decompositions:

53 + 31552139 = 31552192
173 + 31552019 = 31552192
233 + 31551959 = 31552192
251 + 31551941 = 31552192
389 + 31551803 = 31552192
509 + 31551683 = 31552192
521 + 31551671 = 31552192
563 + 31551629 = 31552192

Showing the first eight; more decompositions exist.
