Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573952, here are decompositions:

199 + 31573753 = 31573952
313 + 31573639 = 31573952
331 + 31573621 = 31573952
439 + 31573513 = 31573952
673 + 31573279 = 31573952
691 + 31573261 = 31573952
829 + 31573123 = 31573952
859 + 31573093 = 31573952

Showing the first eight; more decompositions exist.
