Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531046, here are decompositions:

67 + 31530979 = 31531046
73 + 31530973 = 31531046
103 + 31530943 = 31531046
367 + 31530679 = 31531046
397 + 31530649 = 31531046
409 + 31530637 = 31531046
439 + 31530607 = 31531046
457 + 31530589 = 31531046

Showing the first eight; more decompositions exist.
