Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489262, here are decompositions:

3 + 31489259 = 31489262
19 + 31489243 = 31489262
193 + 31489069 = 31489262
199 + 31489063 = 31489262
271 + 31488991 = 31489262
283 + 31488979 = 31489262
331 + 31488931 = 31489262
463 + 31488799 = 31489262

Showing the first eight; more decompositions exist.
