Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615594, here are decompositions:

5 + 31615589 = 31615594
11 + 31615583 = 31615594
191 + 31615403 = 31615594
251 + 31615343 = 31615594
281 + 31615313 = 31615594
383 + 31615211 = 31615594
401 + 31615193 = 31615594
431 + 31615163 = 31615594

Showing the first eight; more decompositions exist.
