Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452846, here are decompositions:

17 + 31452829 = 31452846
43 + 31452803 = 31452846
53 + 31452793 = 31452846
83 + 31452763 = 31452846
97 + 31452749 = 31452846
107 + 31452739 = 31452846
127 + 31452719 = 31452846
163 + 31452683 = 31452846

Showing the first eight; more decompositions exist.
