Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532486, here are decompositions:

157 + 31532329 = 31532486
163 + 31532323 = 31532486
277 + 31532209 = 31532486
283 + 31532203 = 31532486
373 + 31532113 = 31532486
397 + 31532089 = 31532486
577 + 31531909 = 31532486
673 + 31531813 = 31532486

Showing the first eight; more decompositions exist.
