Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517534, here are decompositions:

7 + 31517527 = 31517534
43 + 31517491 = 31517534
67 + 31517467 = 31517534
127 + 31517407 = 31517534
337 + 31517197 = 31517534
523 + 31517011 = 31517534
541 + 31516993 = 31517534
757 + 31516777 = 31517534

Showing the first eight; more decompositions exist.
