Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588254, here are decompositions:

7 + 31588247 = 31588254
53 + 31588201 = 31588254
83 + 31588171 = 31588254
97 + 31588157 = 31588254
151 + 31588103 = 31588254
167 + 31588087 = 31588254
193 + 31588061 = 31588254
251 + 31588003 = 31588254

Showing the first eight; more decompositions exist.
