Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503792, here are decompositions:

13 + 31503779 = 31503792
41 + 31503751 = 31503792
43 + 31503749 = 31503792
59 + 31503733 = 31503792
79 + 31503713 = 31503792
149 + 31503643 = 31503792
223 + 31503569 = 31503792
233 + 31503559 = 31503792

Showing the first eight; more decompositions exist.
