Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513462, here are decompositions:

59 + 31513403 = 31513462
89 + 31513373 = 31513462
131 + 31513331 = 31513462
269 + 31513193 = 31513462
389 + 31513073 = 31513462
503 + 31512959 = 31513462
569 + 31512893 = 31513462
593 + 31512869 = 31513462

Showing the first eight; more decompositions exist.
