Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532862, here are decompositions:

29 + 31532833 = 31532862
113 + 31532749 = 31532862
223 + 31532639 = 31532862
269 + 31532593 = 31532862
281 + 31532581 = 31532862
311 + 31532551 = 31532862
373 + 31532489 = 31532862
433 + 31532429 = 31532862

Showing the first eight; more decompositions exist.
