Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522776, here are decompositions:

29 + 31522747 = 31522776
59 + 31522717 = 31522776
83 + 31522693 = 31522776
107 + 31522669 = 31522776
113 + 31522663 = 31522776
163 + 31522613 = 31522776
179 + 31522597 = 31522776
193 + 31522583 = 31522776

Showing the first eight; more decompositions exist.
