Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489022, here are decompositions:

13 + 31489009 = 31489022
31 + 31488991 = 31489022
43 + 31488979 = 31489022
163 + 31488859 = 31489022
223 + 31488799 = 31489022
541 + 31488481 = 31489022
751 + 31488271 = 31489022
811 + 31488211 = 31489022

Showing the first eight; more decompositions exist.
