Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480614, here are decompositions:

107 + 31480507 = 31480614
173 + 31480441 = 31480614
181 + 31480433 = 31480614
223 + 31480391 = 31480614
233 + 31480381 = 31480614
241 + 31480373 = 31480614
523 + 31480091 = 31480614
593 + 31480021 = 31480614

Showing the first eight; more decompositions exist.
