Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482784, here are decompositions:

5 + 31482779 = 31482784
23 + 31482761 = 31482784
41 + 31482743 = 31482784
101 + 31482683 = 31482784
167 + 31482617 = 31482784
197 + 31482587 = 31482784
233 + 31482551 = 31482784
383 + 31482401 = 31482784

Showing the first eight; more decompositions exist.
