Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532064, here are decompositions:

43 + 31532021 = 31532064
61 + 31532003 = 31532064
97 + 31531967 = 31532064
181 + 31531883 = 31532064
251 + 31531813 = 31532064
313 + 31531751 = 31532064
337 + 31531727 = 31532064
397 + 31531667 = 31532064

Showing the first eight; more decompositions exist.
