Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462848, here are decompositions:

17 + 31462831 = 31462848
37 + 31462811 = 31462848
41 + 31462807 = 31462848
89 + 31462759 = 31462848
97 + 31462751 = 31462848
101 + 31462747 = 31462848
199 + 31462649 = 31462848
239 + 31462609 = 31462848

Showing the first eight; more decompositions exist.
