Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588796, here are decompositions:

97 + 31588699 = 31588796
103 + 31588693 = 31588796
139 + 31588657 = 31588796
193 + 31588603 = 31588796
313 + 31588483 = 31588796
397 + 31588399 = 31588796
439 + 31588357 = 31588796
709 + 31588087 = 31588796

Showing the first eight; more decompositions exist.
