Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573718, here are decompositions:

79 + 31573639 = 31573718
97 + 31573621 = 31573718
157 + 31573561 = 31573718
439 + 31573279 = 31573718
457 + 31573261 = 31573718
607 + 31573111 = 31573718
661 + 31573057 = 31573718
691 + 31573027 = 31573718

Showing the first eight; more decompositions exist.
