Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534746, here are decompositions:

7 + 31534739 = 31534746
17 + 31534729 = 31534746
37 + 31534709 = 31534746
109 + 31534637 = 31534746
149 + 31534597 = 31534746
157 + 31534589 = 31534746
193 + 31534553 = 31534746
263 + 31534483 = 31534746

Showing the first eight; more decompositions exist.
