Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535888, here are decompositions:

61 + 31535827 = 31535888
67 + 31535821 = 31535888
79 + 31535809 = 31535888
337 + 31535551 = 31535888
421 + 31535467 = 31535888
547 + 31535341 = 31535888
577 + 31535311 = 31535888
661 + 31535227 = 31535888

Showing the first eight; more decompositions exist.
