Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532098, here are decompositions:

131 + 31531967 = 31532098
167 + 31531931 = 31532098
281 + 31531817 = 31532098
347 + 31531751 = 31532098
419 + 31531679 = 31532098
431 + 31531667 = 31532098
449 + 31531649 = 31532098
641 + 31531457 = 31532098

Showing the first eight; more decompositions exist.
