Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453358, here are decompositions:

37 + 31453321 = 31453358
109 + 31453249 = 31453358
151 + 31453207 = 31453358
199 + 31453159 = 31453358
337 + 31453021 = 31453358
457 + 31452901 = 31453358
499 + 31452859 = 31453358
619 + 31452739 = 31453358

Showing the first eight; more decompositions exist.
