Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552832, here are decompositions:

139 + 31552693 = 31552832
151 + 31552681 = 31552832
193 + 31552639 = 31552832
211 + 31552621 = 31552832
229 + 31552603 = 31552832
439 + 31552393 = 31552832
523 + 31552309 = 31552832
853 + 31551979 = 31552832

Showing the first eight; more decompositions exist.
