Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460654, here are decompositions:

7 + 31460647 = 31460654
73 + 31460581 = 31460654
103 + 31460551 = 31460654
157 + 31460497 = 31460654
163 + 31460491 = 31460654
223 + 31460431 = 31460654
241 + 31460413 = 31460654
307 + 31460347 = 31460654

Showing the first eight; more decompositions exist.
