Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522962, here are decompositions:

11 + 31522951 = 31522962
61 + 31522901 = 31522962
73 + 31522889 = 31522962
89 + 31522873 = 31522962
139 + 31522823 = 31522962
269 + 31522693 = 31522962
293 + 31522669 = 31522962
349 + 31522613 = 31522962

Showing the first eight; more decompositions exist.
