Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532320, here are decompositions:

41 + 31532279 = 31532320
59 + 31532261 = 31532320
101 + 31532219 = 31532320
179 + 31532141 = 31532320
257 + 31532063 = 31532320
317 + 31532003 = 31532320
353 + 31531967 = 31532320
389 + 31531931 = 31532320

Showing the first eight; more decompositions exist.
