Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480984, here are decompositions:

11 + 31480973 = 31480984
71 + 31480913 = 31480984
83 + 31480901 = 31480984
191 + 31480793 = 31480984
251 + 31480733 = 31480984
593 + 31480391 = 31480984
617 + 31480367 = 31480984
881 + 31480103 = 31480984

Showing the first eight; more decompositions exist.
