Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482874, here are decompositions:

41 + 31482833 = 31482874
53 + 31482821 = 31482874
113 + 31482761 = 31482874
131 + 31482743 = 31482874
167 + 31482707 = 31482874
191 + 31482683 = 31482874
233 + 31482641 = 31482874
257 + 31482617 = 31482874

Showing the first eight; more decompositions exist.
