Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453382, here are decompositions:

61 + 31453321 = 31453382
211 + 31453171 = 31453382
223 + 31453159 = 31453382
241 + 31453141 = 31453382
409 + 31452973 = 31453382
439 + 31452943 = 31453382
523 + 31452859 = 31453382
613 + 31452769 = 31453382

Showing the first eight; more decompositions exist.
