Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627184, here are decompositions:

151 + 31627033 = 31627184
157 + 31627027 = 31627184
241 + 31626943 = 31627184
397 + 31626787 = 31627184
577 + 31626607 = 31627184
613 + 31626571 = 31627184
691 + 31626493 = 31627184
937 + 31626247 = 31627184

Showing the first eight; more decompositions exist.
