Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530734, here are decompositions:

31 + 31530703 = 31530734
73 + 31530661 = 31530734
97 + 31530637 = 31530734
127 + 31530607 = 31530734
163 + 31530571 = 31530734
211 + 31530523 = 31530734
283 + 31530451 = 31530734
523 + 31530211 = 31530734

Showing the first eight; more decompositions exist.
