Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480344, here are decompositions:

227 + 31480117 = 31480344
241 + 31480103 = 31480344
283 + 31480061 = 31480344
383 + 31479961 = 31480344
397 + 31479947 = 31480344
463 + 31479881 = 31480344
487 + 31479857 = 31480344
523 + 31479821 = 31480344

Showing the first eight; more decompositions exist.
