Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510434, here are decompositions:

31 + 31510403 = 31510434
37 + 31510397 = 31510434
47 + 31510387 = 31510434
71 + 31510363 = 31510434
113 + 31510321 = 31510434
191 + 31510243 = 31510434
211 + 31510223 = 31510434
313 + 31510121 = 31510434

Showing the first eight; more decompositions exist.
