Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489294, here are decompositions:

47 + 31489247 = 31489294
101 + 31489193 = 31489294
113 + 31489181 = 31489294
197 + 31489097 = 31489294
251 + 31489043 = 31489294
257 + 31489037 = 31489294
383 + 31488911 = 31489294
467 + 31488827 = 31489294

Showing the first eight; more decompositions exist.
