Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453682, here are decompositions:

3 + 31453679 = 31453682
31 + 31453651 = 31453682
181 + 31453501 = 31453682
199 + 31453483 = 31453682
349 + 31453333 = 31453682
433 + 31453249 = 31453682
523 + 31453159 = 31453682
541 + 31453141 = 31453682

Showing the first eight; more decompositions exist.
