Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531058, here are decompositions:

79 + 31530979 = 31531058
157 + 31530901 = 31531058
379 + 31530679 = 31531058
397 + 31530661 = 31531058
409 + 31530649 = 31531058
421 + 31530637 = 31531058
487 + 31530571 = 31531058
571 + 31530487 = 31531058

Showing the first eight; more decompositions exist.
