Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480446, here are decompositions:

5 + 31480441 = 31480446
13 + 31480433 = 31480446
73 + 31480373 = 31480446
79 + 31480367 = 31480446
97 + 31480349 = 31480446
157 + 31480289 = 31480446
317 + 31480129 = 31480446
367 + 31480079 = 31480446

Showing the first eight; more decompositions exist.
