Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542726, here are decompositions:

23 + 31542703 = 31542726
29 + 31542697 = 31542726
67 + 31542659 = 31542726
113 + 31542613 = 31542726
139 + 31542587 = 31542726
167 + 31542559 = 31542726
179 + 31542547 = 31542726
239 + 31542487 = 31542726

Showing the first eight; more decompositions exist.
