Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536262, here are decompositions:

59 + 31536203 = 31536262
101 + 31536161 = 31536262
281 + 31535981 = 31536262
353 + 31535909 = 31536262
383 + 31535879 = 31536262
431 + 31535831 = 31536262
509 + 31535753 = 31536262
521 + 31535741 = 31536262

Showing the first eight; more decompositions exist.
