Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536766, here are decompositions:

47 + 31536719 = 31536766
59 + 31536707 = 31536766
137 + 31536629 = 31536766
227 + 31536539 = 31536766
383 + 31536383 = 31536766
419 + 31536347 = 31536766
479 + 31536287 = 31536766
563 + 31536203 = 31536766

Showing the first eight; more decompositions exist.
