Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527698, here are decompositions:

157 + 31527541 = 31527698
199 + 31527499 = 31527698
421 + 31527277 = 31527698
487 + 31527211 = 31527698
541 + 31527157 = 31527698
547 + 31527151 = 31527698
757 + 31526941 = 31527698
907 + 31526791 = 31527698

Showing the first eight; more decompositions exist.
