Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617754, here are decompositions:

41 + 31617713 = 31617754
167 + 31617587 = 31617754
191 + 31617563 = 31617754
251 + 31617503 = 31617754
257 + 31617497 = 31617754
293 + 31617461 = 31617754
347 + 31617407 = 31617754
383 + 31617371 = 31617754

Showing the first eight; more decompositions exist.
