Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31551062, here are decompositions:

43 + 31551019 = 31551062
139 + 31550923 = 31551062
211 + 31550851 = 31551062
229 + 31550833 = 31551062
271 + 31550791 = 31551062
331 + 31550731 = 31551062
463 + 31550599 = 31551062
523 + 31550539 = 31551062

Showing the first eight; more decompositions exist.
