Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489346, here are decompositions:

67 + 31489279 = 31489346
103 + 31489243 = 31489346
199 + 31489147 = 31489346
277 + 31489069 = 31489346
283 + 31489063 = 31489346
337 + 31489009 = 31489346
367 + 31488979 = 31489346
439 + 31488907 = 31489346

Showing the first eight; more decompositions exist.
