Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460448, here are decompositions:

7 + 31460441 = 31460448
17 + 31460431 = 31460448
79 + 31460369 = 31460448
101 + 31460347 = 31460448
109 + 31460339 = 31460448
127 + 31460321 = 31460448
157 + 31460291 = 31460448
167 + 31460281 = 31460448

Showing the first eight; more decompositions exist.
