Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531034, here are decompositions:

61 + 31530973 = 31531034
193 + 31530841 = 31531034
331 + 31530703 = 31531034
373 + 31530661 = 31531034
397 + 31530637 = 31531034
463 + 31530571 = 31531034
547 + 31530487 = 31531034
643 + 31530391 = 31531034

Showing the first eight; more decompositions exist.
