Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31572584, here are decompositions:

13 + 31572571 = 31572584
61 + 31572523 = 31572584
73 + 31572511 = 31572584
181 + 31572403 = 31572584
283 + 31572301 = 31572584
331 + 31572253 = 31572584
577 + 31572007 = 31572584
601 + 31571983 = 31572584

Showing the first eight; more decompositions exist.
