Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528726, here are decompositions:

3 + 31528723 = 31528726
29 + 31528697 = 31528726
113 + 31528613 = 31528726
167 + 31528559 = 31528726
179 + 31528547 = 31528726
227 + 31528499 = 31528726
293 + 31528433 = 31528726
353 + 31528373 = 31528726

Showing the first eight; more decompositions exist.
