Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31518094, here are decompositions:

5 + 31518089 = 31518094
71 + 31518023 = 31518094
131 + 31517963 = 31518094
233 + 31517861 = 31518094
521 + 31517573 = 31518094
593 + 31517501 = 31518094
653 + 31517441 = 31518094
677 + 31517417 = 31518094

Showing the first eight; more decompositions exist.
