Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489606, here are decompositions:

173 + 31489433 = 31489606
179 + 31489427 = 31489606
257 + 31489349 = 31489606
347 + 31489259 = 31489606
359 + 31489247 = 31489606
389 + 31489217 = 31489606
509 + 31489097 = 31489606
563 + 31489043 = 31489606

Showing the first eight; more decompositions exist.
