Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513546, here are decompositions:

173 + 31513373 = 31513546
353 + 31513193 = 31513546
359 + 31513187 = 31513546
509 + 31513037 = 31513546
587 + 31512959 = 31513546
599 + 31512947 = 31513546
653 + 31512893 = 31513546
677 + 31512869 = 31513546

Showing the first eight; more decompositions exist.
