Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460234, here are decompositions:

37 + 31460197 = 31460234
61 + 31460173 = 31460234
67 + 31460167 = 31460234
97 + 31460137 = 31460234
181 + 31460053 = 31460234
241 + 31459993 = 31460234
271 + 31459963 = 31460234
601 + 31459633 = 31460234

Showing the first eight; more decompositions exist.
