Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534670, here are decompositions:

19 + 31534651 = 31534670
73 + 31534597 = 31534670
109 + 31534561 = 31534670
127 + 31534543 = 31534670
229 + 31534441 = 31534670
241 + 31534429 = 31534670
337 + 31534333 = 31534670
373 + 31534297 = 31534670

Showing the first eight; more decompositions exist.
