Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619698, here are decompositions:

29 + 31619669 = 31619698
137 + 31619561 = 31619698
167 + 31619531 = 31619698
179 + 31619519 = 31619698
197 + 31619501 = 31619698
239 + 31619459 = 31619698
311 + 31619387 = 31619698
431 + 31619267 = 31619698

Showing the first eight; more decompositions exist.
