Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532860, here are decompositions:

83 + 31532777 = 31532860
167 + 31532693 = 31532860
173 + 31532687 = 31532860
263 + 31532597 = 31532860
353 + 31532507 = 31532860
383 + 31532477 = 31532860
431 + 31532429 = 31532860
521 + 31532339 = 31532860

Showing the first eight; more decompositions exist.
