Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453674, here are decompositions:

23 + 31453651 = 31453674
97 + 31453577 = 31453674
103 + 31453571 = 31453674
151 + 31453523 = 31453674
167 + 31453507 = 31453674
173 + 31453501 = 31453674
191 + 31453483 = 31453674
211 + 31453463 = 31453674

Showing the first eight; more decompositions exist.
