Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588736, here are decompositions:

37 + 31588699 = 31588736
43 + 31588693 = 31588736
79 + 31588657 = 31588736
337 + 31588399 = 31588736
367 + 31588369 = 31588736
379 + 31588357 = 31588736
433 + 31588303 = 31588736
607 + 31588129 = 31588736

Showing the first eight; more decompositions exist.
