Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532798, here are decompositions:

61 + 31532737 = 31532798
139 + 31532659 = 31532798
211 + 31532587 = 31532798
277 + 31532521 = 31532798
397 + 31532401 = 31532798
457 + 31532341 = 31532798
571 + 31532227 = 31532798
631 + 31532167 = 31532798

Showing the first eight; more decompositions exist.
