Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536482, here are decompositions:

79 + 31536403 = 31536482
421 + 31536061 = 31536482
433 + 31536049 = 31536482
463 + 31536019 = 31536482
499 + 31535983 = 31536482
541 + 31535941 = 31536482
661 + 31535821 = 31536482
673 + 31535809 = 31536482

Showing the first eight; more decompositions exist.
