Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453550, here are decompositions:

43 + 31453507 = 31453550
67 + 31453483 = 31453550
103 + 31453447 = 31453550
157 + 31453393 = 31453550
229 + 31453321 = 31453550
283 + 31453267 = 31453550
379 + 31453171 = 31453550
409 + 31453141 = 31453550

Showing the first eight; more decompositions exist.
