Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588358, here are decompositions:

7 + 31588351 = 31588358
37 + 31588321 = 31588358
157 + 31588201 = 31588358
229 + 31588129 = 31588358
271 + 31588087 = 31588358
379 + 31587979 = 31588358
397 + 31587961 = 31588358
409 + 31587949 = 31588358

Showing the first eight; more decompositions exist.
