Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568004, here are decompositions:

5 + 31567999 = 31568004
23 + 31567981 = 31568004
43 + 31567961 = 31568004
73 + 31567931 = 31568004
191 + 31567813 = 31568004
263 + 31567741 = 31568004
311 + 31567693 = 31568004
317 + 31567687 = 31568004

Showing the first eight; more decompositions exist.
