Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619526, here are decompositions:

5 + 31619521 = 31619526
7 + 31619519 = 31619526
17 + 31619509 = 31619526
67 + 31619459 = 31619526
137 + 31619389 = 31619526
139 + 31619387 = 31619526
167 + 31619359 = 31619526
199 + 31619327 = 31619526

Showing the first eight; more decompositions exist.
