Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522402, here are decompositions:

29 + 31522373 = 31522402
71 + 31522331 = 31522402
89 + 31522313 = 31522402
173 + 31522229 = 31522402
311 + 31522091 = 31522402
383 + 31522019 = 31522402
389 + 31522013 = 31522402
449 + 31521953 = 31522402

Showing the first eight; more decompositions exist.
