Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489102, here are decompositions:

5 + 31489097 = 31489102
11 + 31489091 = 31489102
23 + 31489079 = 31489102
59 + 31489043 = 31489102
131 + 31488971 = 31489102
191 + 31488911 = 31489102
773 + 31488329 = 31489102
809 + 31488293 = 31489102

Showing the first eight; more decompositions exist.
