Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611850, here are decompositions:

47 + 31611803 = 31611850
89 + 31611761 = 31611850
113 + 31611737 = 31611850
131 + 31611719 = 31611850
191 + 31611659 = 31611850
233 + 31611617 = 31611850
269 + 31611581 = 31611850
311 + 31611539 = 31611850

Showing the first eight; more decompositions exist.
