Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559762, here are decompositions:

43 + 31559719 = 31559762
103 + 31559659 = 31559762
109 + 31559653 = 31559762
139 + 31559623 = 31559762
349 + 31559413 = 31559762
379 + 31559383 = 31559762
499 + 31559263 = 31559762
523 + 31559239 = 31559762

Showing the first eight; more decompositions exist.
