Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522930, here are decompositions:

29 + 31522901 = 31522930
41 + 31522889 = 31522930
83 + 31522847 = 31522930
107 + 31522823 = 31522930
317 + 31522613 = 31522930
347 + 31522583 = 31522930
389 + 31522541 = 31522930
401 + 31522529 = 31522930

Showing the first eight; more decompositions exist.
