Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469698, here are decompositions:

137 + 31469561 = 31469698
167 + 31469531 = 31469698
179 + 31469519 = 31469698
251 + 31469447 = 31469698
257 + 31469441 = 31469698
311 + 31469387 = 31469698
419 + 31469279 = 31469698
521 + 31469177 = 31469698

Showing the first eight; more decompositions exist.
