Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536418, here are decompositions:

59 + 31536359 = 31536418
71 + 31536347 = 31536418
131 + 31536287 = 31536418
191 + 31536227 = 31536418
257 + 31536161 = 31536418
317 + 31536101 = 31536418
401 + 31536017 = 31536418
479 + 31535939 = 31536418

Showing the first eight; more decompositions exist.
