Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489110, here are decompositions:

13 + 31489097 = 31489110
19 + 31489091 = 31489110
31 + 31489079 = 31489110
41 + 31489069 = 31489110
47 + 31489063 = 31489110
67 + 31489043 = 31489110
73 + 31489037 = 31489110
83 + 31489027 = 31489110

Showing the first eight; more decompositions exist.
