Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611534, here are decompositions:

7 + 31611527 = 31611534
47 + 31611487 = 31611534
61 + 31611473 = 31611534
67 + 31611467 = 31611534
131 + 31611403 = 31611534
167 + 31611367 = 31611534
193 + 31611341 = 31611534
211 + 31611323 = 31611534

Showing the first eight; more decompositions exist.
