Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534648, here are decompositions:

11 + 31534637 = 31534648
17 + 31534631 = 31534648
59 + 31534589 = 31534648
191 + 31534457 = 31534648
347 + 31534301 = 31534648
401 + 31534247 = 31534648
449 + 31534199 = 31534648
461 + 31534187 = 31534648

Showing the first eight; more decompositions exist.
