Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482774, here are decompositions:

13 + 31482761 = 31482774
31 + 31482743 = 31482774
67 + 31482707 = 31482774
107 + 31482667 = 31482774
131 + 31482643 = 31482774
157 + 31482617 = 31482774
223 + 31482551 = 31482774
263 + 31482511 = 31482774

Showing the first eight; more decompositions exist.
