Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496242, here are decompositions:

23 + 31496219 = 31496242
101 + 31496141 = 31496242
263 + 31495979 = 31496242
293 + 31495949 = 31496242
383 + 31495859 = 31496242
509 + 31495733 = 31496242
641 + 31495601 = 31496242
653 + 31495589 = 31496242

Showing the first eight; more decompositions exist.
