Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494582, here are decompositions:

29 + 31494553 = 31494582
73 + 31494509 = 31494582
79 + 31494503 = 31494582
103 + 31494479 = 31494582
113 + 31494469 = 31494582
139 + 31494443 = 31494582
151 + 31494431 = 31494582
181 + 31494401 = 31494582

Showing the first eight; more decompositions exist.
