Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611718, here are decompositions:

59 + 31611659 = 31611718
71 + 31611647 = 31611718
101 + 31611617 = 31611718
137 + 31611581 = 31611718
179 + 31611539 = 31611718
191 + 31611527 = 31611718
251 + 31611467 = 31611718
389 + 31611329 = 31611718

Showing the first eight; more decompositions exist.
