Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31518034, here are decompositions:

3 + 31518031 = 31518034
11 + 31518023 = 31518034
71 + 31517963 = 31518034
83 + 31517951 = 31518034
173 + 31517861 = 31518034
311 + 31517723 = 31518034
461 + 31517573 = 31518034
491 + 31517543 = 31518034

Showing the first eight; more decompositions exist.
