Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535876, here are decompositions:

67 + 31535809 = 31535876
79 + 31535797 = 31535876
283 + 31535593 = 31535876
373 + 31535503 = 31535876
409 + 31535467 = 31535876
457 + 31535419 = 31535876
499 + 31535377 = 31535876
613 + 31535263 = 31535876

Showing the first eight; more decompositions exist.
