Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460974, here are decompositions:

3 + 31460971 = 31460974
23 + 31460951 = 31460974
47 + 31460927 = 31460974
101 + 31460873 = 31460974
137 + 31460837 = 31460974
191 + 31460783 = 31460974
257 + 31460717 = 31460974
317 + 31460657 = 31460974

Showing the first eight; more decompositions exist.
