Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522430, here are decompositions:

19 + 31522411 = 31522430
67 + 31522363 = 31522430
73 + 31522357 = 31522430
103 + 31522327 = 31522430
211 + 31522219 = 31522430
223 + 31522207 = 31522430
409 + 31522021 = 31522430
439 + 31521991 = 31522430

Showing the first eight; more decompositions exist.
