Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31518026, here are decompositions:

3 + 31518023 = 31518026
19 + 31518007 = 31518026
73 + 31517953 = 31518026
139 + 31517887 = 31518026
277 + 31517749 = 31518026
373 + 31517653 = 31518026
409 + 31517617 = 31518026
439 + 31517587 = 31518026

Showing the first eight; more decompositions exist.
