Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453074, here are decompositions:

53 + 31453021 = 31453074
97 + 31452977 = 31453074
101 + 31452973 = 31453074
131 + 31452943 = 31453074
173 + 31452901 = 31453074
223 + 31452851 = 31453074
271 + 31452803 = 31453074
281 + 31452793 = 31453074

Showing the first eight; more decompositions exist.
