Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522358, here are decompositions:

19 + 31522339 = 31522358
31 + 31522327 = 31522358
61 + 31522297 = 31522358
139 + 31522219 = 31522358
151 + 31522207 = 31522358
229 + 31522129 = 31522358
337 + 31522021 = 31522358
367 + 31521991 = 31522358

Showing the first eight; more decompositions exist.
