Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619024, here are decompositions:

7 + 31619017 = 31619024
43 + 31618981 = 31619024
127 + 31618897 = 31619024
271 + 31618753 = 31619024
313 + 31618711 = 31619024
331 + 31618693 = 31619024
457 + 31618567 = 31619024
601 + 31618423 = 31619024

Showing the first eight; more decompositions exist.
