Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539026, here are decompositions:

19 + 31539007 = 31539026
139 + 31538887 = 31539026
199 + 31538827 = 31539026
283 + 31538743 = 31539026
307 + 31538719 = 31539026
313 + 31538713 = 31539026
373 + 31538653 = 31539026
397 + 31538629 = 31539026

Showing the first eight; more decompositions exist.
