Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558924, here are decompositions:

41 + 31558883 = 31558924
101 + 31558823 = 31558924
191 + 31558733 = 31558924
251 + 31558673 = 31558924
317 + 31558607 = 31558924
461 + 31558463 = 31558924
491 + 31558433 = 31558924
587 + 31558337 = 31558924

Showing the first eight; more decompositions exist.
