Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453292, here are decompositions:

43 + 31453249 = 31453292
151 + 31453141 = 31453292
271 + 31453021 = 31453292
349 + 31452943 = 31453292
433 + 31452859 = 31453292
463 + 31452829 = 31453292
499 + 31452793 = 31453292
523 + 31452769 = 31453292

Showing the first eight; more decompositions exist.
