Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453670, here are decompositions:

19 + 31453651 = 31453670
163 + 31453507 = 31453670
223 + 31453447 = 31453670
277 + 31453393 = 31453670
337 + 31453333 = 31453670
349 + 31453321 = 31453670
421 + 31453249 = 31453670
463 + 31453207 = 31453670

Showing the first eight; more decompositions exist.
