Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534928, here are decompositions:

97 + 31534831 = 31534928
109 + 31534819 = 31534928
127 + 31534801 = 31534928
199 + 31534729 = 31534928
277 + 31534651 = 31534928
331 + 31534597 = 31534928
367 + 31534561 = 31534928
487 + 31534441 = 31534928

Showing the first eight; more decompositions exist.
