Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460174, here are decompositions:

7 + 31460167 = 31460174
37 + 31460137 = 31460174
157 + 31460017 = 31460174
181 + 31459993 = 31460174
211 + 31459963 = 31460174
283 + 31459891 = 31460174
367 + 31459807 = 31460174
457 + 31459717 = 31460174

Showing the first eight; more decompositions exist.
