Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588484, here are decompositions:

13 + 31588471 = 31588484
43 + 31588441 = 31588484
127 + 31588357 = 31588484
163 + 31588321 = 31588484
181 + 31588303 = 31588484
283 + 31588201 = 31588484
313 + 31588171 = 31588484
397 + 31588087 = 31588484

Showing the first eight; more decompositions exist.
