Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452792, here are decompositions:

23 + 31452769 = 31452792
29 + 31452763 = 31452792
43 + 31452749 = 31452792
53 + 31452739 = 31452792
61 + 31452731 = 31452792
71 + 31452721 = 31452792
73 + 31452719 = 31452792
109 + 31452683 = 31452792

Showing the first eight; more decompositions exist.
