Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532076, here are decompositions:

5 + 31532071 = 31532076
13 + 31532063 = 31532076
73 + 31532003 = 31532076
109 + 31531967 = 31532076
167 + 31531909 = 31532076
193 + 31531883 = 31532076
263 + 31531813 = 31532076
349 + 31531727 = 31532076

Showing the first eight; more decompositions exist.
