Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619264, here are decompositions:

3 + 31619261 = 31619264
7 + 31619257 = 31619264
73 + 31619191 = 31619264
223 + 31619041 = 31619264
283 + 31618981 = 31619264
367 + 31618897 = 31619264
373 + 31618891 = 31619264
487 + 31618777 = 31619264

Showing the first eight; more decompositions exist.
