Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532470, here are decompositions:

41 + 31532429 = 31532470
131 + 31532339 = 31532470
191 + 31532279 = 31532470
251 + 31532219 = 31532470
353 + 31532117 = 31532470
449 + 31532021 = 31532470
467 + 31532003 = 31532470
503 + 31531967 = 31532470

Showing the first eight; more decompositions exist.
