Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522436, here are decompositions:

3 + 31522433 = 31522436
73 + 31522363 = 31522436
79 + 31522357 = 31522436
97 + 31522339 = 31522436
109 + 31522327 = 31522436
139 + 31522297 = 31522436
193 + 31522243 = 31522436
229 + 31522207 = 31522436

Showing the first eight; more decompositions exist.
