Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522842, here are decompositions:

19 + 31522823 = 31522842
149 + 31522693 = 31522842
173 + 31522669 = 31522842
179 + 31522663 = 31522842
229 + 31522613 = 31522842
251 + 31522591 = 31522842
293 + 31522549 = 31522842
313 + 31522529 = 31522842

Showing the first eight; more decompositions exist.
