Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541924, here are decompositions:

31 + 31541893 = 31541924
67 + 31541857 = 31541924
97 + 31541827 = 31541924
163 + 31541761 = 31541924
313 + 31541611 = 31541924
367 + 31541557 = 31541924
397 + 31541527 = 31541924
457 + 31541467 = 31541924

Showing the first eight; more decompositions exist.
