Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534912, here are decompositions:

41 + 31534871 = 31534912
113 + 31534799 = 31534912
173 + 31534739 = 31534912
281 + 31534631 = 31534912
359 + 31534553 = 31534912
419 + 31534493 = 31534912
569 + 31534343 = 31534912
641 + 31534271 = 31534912

Showing the first eight; more decompositions exist.
