Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532276, here are decompositions:

7 + 31532269 = 31532276
67 + 31532209 = 31532276
73 + 31532203 = 31532276
109 + 31532167 = 31532276
163 + 31532113 = 31532276
367 + 31531909 = 31532276
463 + 31531813 = 31532276
823 + 31531453 = 31532276

Showing the first eight; more decompositions exist.
