Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493582, here are decompositions:

13 + 31493569 = 31493582
61 + 31493521 = 31493582
139 + 31493443 = 31493582
163 + 31493419 = 31493582
229 + 31493353 = 31493582
331 + 31493251 = 31493582
499 + 31493083 = 31493582
619 + 31492963 = 31493582

Showing the first eight; more decompositions exist.
