Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573358, here are decompositions:

79 + 31573279 = 31573358
97 + 31573261 = 31573358
331 + 31573027 = 31573358
337 + 31573021 = 31573358
379 + 31572979 = 31573358
409 + 31572949 = 31573358
457 + 31572901 = 31573358
631 + 31572727 = 31573358

Showing the first eight; more decompositions exist.
