Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31518594, here are decompositions:

5 + 31518589 = 31518594
53 + 31518541 = 31518594
71 + 31518523 = 31518594
73 + 31518521 = 31518594
103 + 31518491 = 31518594
113 + 31518481 = 31518594
127 + 31518467 = 31518594
137 + 31518457 = 31518594

Showing the first eight; more decompositions exist.
