Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536838, here are decompositions:

17 + 31536821 = 31536838
107 + 31536731 = 31536838
131 + 31536707 = 31536838
317 + 31536521 = 31536838
479 + 31536359 = 31536838
491 + 31536347 = 31536838
677 + 31536161 = 31536838
821 + 31536017 = 31536838

Showing the first eight; more decompositions exist.
