Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522980, here are decompositions:

19 + 31522961 = 31522980
29 + 31522951 = 31522980
43 + 31522937 = 31522980
79 + 31522901 = 31522980
107 + 31522873 = 31522980
157 + 31522823 = 31522980
233 + 31522747 = 31522980
263 + 31522717 = 31522980

Showing the first eight; more decompositions exist.
