Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482946, here are decompositions:

107 + 31482839 = 31482946
113 + 31482833 = 31482946
167 + 31482779 = 31482946
239 + 31482707 = 31482946
263 + 31482683 = 31482946
347 + 31482599 = 31482946
359 + 31482587 = 31482946
557 + 31482389 = 31482946

Showing the first eight; more decompositions exist.
