Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494024, here are decompositions:

41 + 31493983 = 31494024
73 + 31493951 = 31494024
83 + 31493941 = 31494024
97 + 31493927 = 31494024
167 + 31493857 = 31494024
173 + 31493851 = 31494024
241 + 31493783 = 31494024
281 + 31493743 = 31494024

Showing the first eight; more decompositions exist.
