Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536742, here are decompositions:

11 + 31536731 = 31536742
23 + 31536719 = 31536742
113 + 31536629 = 31536742
191 + 31536551 = 31536742
359 + 31536383 = 31536742
383 + 31536359 = 31536742
389 + 31536353 = 31536742
449 + 31536293 = 31536742

Showing the first eight; more decompositions exist.
