Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453418, here are decompositions:

97 + 31453321 = 31453418
151 + 31453267 = 31453418
211 + 31453207 = 31453418
277 + 31453141 = 31453418
379 + 31453039 = 31453418
397 + 31453021 = 31453418
691 + 31452727 = 31453418
751 + 31452667 = 31453418

Showing the first eight; more decompositions exist.
