Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619544, here are decompositions:

13 + 31619531 = 31619544
17 + 31619527 = 31619544
23 + 31619521 = 31619544
43 + 31619501 = 31619544
137 + 31619407 = 31619544
157 + 31619387 = 31619544
233 + 31619311 = 31619544
263 + 31619281 = 31619544

Showing the first eight; more decompositions exist.
