Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535882, here are decompositions:

3 + 31535879 = 31535882
61 + 31535821 = 31535882
73 + 31535809 = 31535882
211 + 31535671 = 31535882
331 + 31535551 = 31535882
379 + 31535503 = 31535882
463 + 31535419 = 31535882
541 + 31535341 = 31535882

Showing the first eight; more decompositions exist.
