Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513576, here are decompositions:

173 + 31513403 = 31513576
317 + 31513259 = 31513576
383 + 31513193 = 31513576
389 + 31513187 = 31513576
503 + 31513073 = 31513576
569 + 31513007 = 31513576
617 + 31512959 = 31513576
683 + 31512893 = 31513576

Showing the first eight; more decompositions exist.
