Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449848, here are decompositions:

97 + 31449751 = 31449848
109 + 31449739 = 31449848
151 + 31449697 = 31449848
211 + 31449637 = 31449848
229 + 31449619 = 31449848
271 + 31449577 = 31449848
277 + 31449571 = 31449848
349 + 31449499 = 31449848

Showing the first eight; more decompositions exist.
