Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31572104, here are decompositions:

97 + 31572007 = 31572104
271 + 31571833 = 31572104
283 + 31571821 = 31572104
373 + 31571731 = 31572104
397 + 31571707 = 31572104
457 + 31571647 = 31572104
547 + 31571557 = 31572104
607 + 31571497 = 31572104

Showing the first eight; more decompositions exist.
