Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532842, here are decompositions:

149 + 31532693 = 31532842
269 + 31532573 = 31532842
353 + 31532489 = 31532842
503 + 31532339 = 31532842
563 + 31532279 = 31532842
701 + 31532141 = 31532842
821 + 31532021 = 31532842
839 + 31532003 = 31532842

Showing the first eight; more decompositions exist.
