Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480924, here are decompositions:

5 + 31480919 = 31480924
11 + 31480913 = 31480924
23 + 31480901 = 31480924
131 + 31480793 = 31480924
191 + 31480733 = 31480924
491 + 31480433 = 31480924
557 + 31480367 = 31480924
821 + 31480103 = 31480924

Showing the first eight; more decompositions exist.
