Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534642, here are decompositions:

5 + 31534637 = 31534642
11 + 31534631 = 31534642
53 + 31534589 = 31534642
89 + 31534553 = 31534642
149 + 31534493 = 31534642
401 + 31534241 = 31534642
443 + 31534199 = 31534642
521 + 31534121 = 31534642

Showing the first eight; more decompositions exist.
