Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534934, here are decompositions:

61 + 31534873 = 31534934
103 + 31534831 = 31534934
181 + 31534753 = 31534934
283 + 31534651 = 31534934
337 + 31534597 = 31534934
373 + 31534561 = 31534934
433 + 31534501 = 31534934
523 + 31534411 = 31534934

Showing the first eight; more decompositions exist.
