Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489350, here are decompositions:

71 + 31489279 = 31489350
103 + 31489247 = 31489350
107 + 31489243 = 31489350
157 + 31489193 = 31489350
173 + 31489177 = 31489350
181 + 31489169 = 31489350
271 + 31489079 = 31489350
281 + 31489069 = 31489350

Showing the first eight; more decompositions exist.
