Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535962, here are decompositions:

23 + 31535939 = 31535962
53 + 31535909 = 31535962
83 + 31535879 = 31535962
131 + 31535831 = 31535962
281 + 31535681 = 31535962
641 + 31535321 = 31535962
743 + 31535219 = 31535962
839 + 31535123 = 31535962

Showing the first eight; more decompositions exist.
