Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588446, here are decompositions:

5 + 31588441 = 31588446
7 + 31588439 = 31588446
47 + 31588399 = 31588446
79 + 31588367 = 31588446
89 + 31588357 = 31588446
139 + 31588307 = 31588446
179 + 31588267 = 31588446
193 + 31588253 = 31588446

Showing the first eight; more decompositions exist.
