Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526698, here are decompositions:

29 + 31526669 = 31526698
311 + 31526387 = 31526698
347 + 31526351 = 31526698
491 + 31526207 = 31526698
509 + 31526189 = 31526698
557 + 31526141 = 31526698
641 + 31526057 = 31526698
647 + 31526051 = 31526698

Showing the first eight; more decompositions exist.
