Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482792, here are decompositions:

13 + 31482779 = 31482792
31 + 31482761 = 31482792
83 + 31482709 = 31482792
109 + 31482683 = 31482792
149 + 31482643 = 31482792
151 + 31482641 = 31482792
179 + 31482613 = 31482792
193 + 31482599 = 31482792

Showing the first eight; more decompositions exist.
