Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453598, here are decompositions:

97 + 31453501 = 31453598
151 + 31453447 = 31453598
277 + 31453321 = 31453598
331 + 31453267 = 31453598
349 + 31453249 = 31453598
439 + 31453159 = 31453598
457 + 31453141 = 31453598
577 + 31453021 = 31453598

Showing the first eight; more decompositions exist.
