Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567874, here are decompositions:

61 + 31567813 = 31567874
157 + 31567717 = 31567874
181 + 31567693 = 31567874
193 + 31567681 = 31567874
271 + 31567603 = 31567874
463 + 31567411 = 31567874
577 + 31567297 = 31567874
607 + 31567267 = 31567874

Showing the first eight; more decompositions exist.
