Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489362, here are decompositions:

13 + 31489349 = 31489362
83 + 31489279 = 31489362
103 + 31489259 = 31489362
181 + 31489181 = 31489362
193 + 31489169 = 31489362
271 + 31489091 = 31489362
283 + 31489079 = 31489362
293 + 31489069 = 31489362

Showing the first eight; more decompositions exist.
