Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534838, here are decompositions:

7 + 31534831 = 31534838
19 + 31534819 = 31534838
37 + 31534801 = 31534838
109 + 31534729 = 31534838
241 + 31534597 = 31534838
277 + 31534561 = 31534838
337 + 31534501 = 31534838
397 + 31534441 = 31534838

Showing the first eight; more decompositions exist.
