Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617430, here are decompositions:

17 + 31617413 = 31617430
23 + 31617407 = 31617430
59 + 31617371 = 31617430
101 + 31617329 = 31617430
137 + 31617293 = 31617430
149 + 31617281 = 31617430
179 + 31617251 = 31617430
191 + 31617239 = 31617430

Showing the first eight; more decompositions exist.
