Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489534, here are decompositions:

71 + 31489463 = 31489534
101 + 31489433 = 31489534
107 + 31489427 = 31489534
317 + 31489217 = 31489534
353 + 31489181 = 31489534
443 + 31489091 = 31489534
491 + 31489043 = 31489534
563 + 31488971 = 31489534

Showing the first eight; more decompositions exist.
