Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522796, here are decompositions:

79 + 31522717 = 31522796
103 + 31522693 = 31522796
127 + 31522669 = 31522796
139 + 31522657 = 31522796
163 + 31522633 = 31522796
199 + 31522597 = 31522796
337 + 31522459 = 31522796
433 + 31522363 = 31522796

Showing the first eight; more decompositions exist.
