Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31518076, here are decompositions:

53 + 31518023 = 31518076
113 + 31517963 = 31518076
167 + 31517909 = 31518076
197 + 31517879 = 31518076
347 + 31517729 = 31518076
353 + 31517723 = 31518076
479 + 31517597 = 31518076
503 + 31517573 = 31518076

Showing the first eight; more decompositions exist.
