Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452774, here are decompositions:

5 + 31452769 = 31452774
11 + 31452763 = 31452774
43 + 31452731 = 31452774
47 + 31452727 = 31452774
53 + 31452721 = 31452774
97 + 31452677 = 31452774
107 + 31452667 = 31452774
151 + 31452623 = 31452774

Showing the first eight; more decompositions exist.
