Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452906, here are decompositions:

5 + 31452901 = 31452906
47 + 31452859 = 31452906
103 + 31452803 = 31452906
113 + 31452793 = 31452906
137 + 31452769 = 31452906
157 + 31452749 = 31452906
167 + 31452739 = 31452906
179 + 31452727 = 31452906

Showing the first eight; more decompositions exist.
