Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619374, here are decompositions:

47 + 31619327 = 31619374
107 + 31619267 = 31619374
113 + 31619261 = 31619374
167 + 31619207 = 31619374
191 + 31619183 = 31619374
197 + 31619177 = 31619374
251 + 31619123 = 31619374
257 + 31619117 = 31619374

Showing the first eight; more decompositions exist.
