Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483792, here are decompositions:

3 + 31483789 = 31483792
59 + 31483733 = 31483792
101 + 31483691 = 31483792
239 + 31483553 = 31483792
359 + 31483433 = 31483792
401 + 31483391 = 31483792
479 + 31483313 = 31483792
563 + 31483229 = 31483792

Showing the first eight; more decompositions exist.
