Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489074, here are decompositions:

5 + 31489069 = 31489074
11 + 31489063 = 31489074
31 + 31489043 = 31489074
37 + 31489037 = 31489074
47 + 31489027 = 31489074
83 + 31488991 = 31489074
103 + 31488971 = 31489074
157 + 31488917 = 31489074

Showing the first eight; more decompositions exist.
