Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452894, here are decompositions:

43 + 31452851 = 31452894
101 + 31452793 = 31452894
131 + 31452763 = 31452894
163 + 31452731 = 31452894
167 + 31452727 = 31452894
173 + 31452721 = 31452894
211 + 31452683 = 31452894
227 + 31452667 = 31452894

Showing the first eight; more decompositions exist.
