Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615546, here are decompositions:

3 + 31615543 = 31615546
107 + 31615439 = 31615546
233 + 31615313 = 31615546
317 + 31615229 = 31615546
353 + 31615193 = 31615546
359 + 31615187 = 31615546
383 + 31615163 = 31615546
419 + 31615127 = 31615546

Showing the first eight; more decompositions exist.
