Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588544, here are decompositions:

61 + 31588483 = 31588544
73 + 31588471 = 31588544
103 + 31588441 = 31588544
193 + 31588351 = 31588544
223 + 31588321 = 31588544
241 + 31588303 = 31588544
277 + 31588267 = 31588544
373 + 31588171 = 31588544

Showing the first eight; more decompositions exist.
