Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480608, here are decompositions:

79 + 31480529 = 31480608
101 + 31480507 = 31480608
167 + 31480441 = 31480608
227 + 31480381 = 31480608
239 + 31480369 = 31480608
241 + 31480367 = 31480608
349 + 31480259 = 31480608
479 + 31480129 = 31480608

Showing the first eight; more decompositions exist.
