Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611862, here are decompositions:

11 + 31611851 = 31611862
59 + 31611803 = 31611862
101 + 31611761 = 31611862
281 + 31611581 = 31611862
353 + 31611509 = 31611862
389 + 31611473 = 31611862
521 + 31611341 = 31611862
563 + 31611299 = 31611862

Showing the first eight; more decompositions exist.
