Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619524, here are decompositions:

3 + 31619521 = 31619524
5 + 31619519 = 31619524
23 + 31619501 = 31619524
137 + 31619387 = 31619524
197 + 31619327 = 31619524
257 + 31619267 = 31619524
263 + 31619261 = 31619524
311 + 31619213 = 31619524

Showing the first eight; more decompositions exist.
