Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588454, here are decompositions:

13 + 31588441 = 31588454
97 + 31588357 = 31588454
103 + 31588351 = 31588454
151 + 31588303 = 31588454
283 + 31588171 = 31588454
367 + 31588087 = 31588454
577 + 31587877 = 31588454
661 + 31587793 = 31588454

Showing the first eight; more decompositions exist.
