Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31519582, here are decompositions:

11 + 31519571 = 31519582
179 + 31519403 = 31519582
293 + 31519289 = 31519582
383 + 31519199 = 31519582
389 + 31519193 = 31519582
401 + 31519181 = 31519582
431 + 31519151 = 31519582
461 + 31519121 = 31519582

Showing the first eight; more decompositions exist.
