Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522886, here are decompositions:

13 + 31522873 = 31522886
139 + 31522747 = 31522886
193 + 31522693 = 31522886
223 + 31522663 = 31522886
229 + 31522657 = 31522886
337 + 31522549 = 31522886
523 + 31522363 = 31522886
547 + 31522339 = 31522886

Showing the first eight; more decompositions exist.
