Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562448, here are decompositions:

7 + 31562441 = 31562448
17 + 31562431 = 31562448
19 + 31562429 = 31562448
59 + 31562389 = 31562448
101 + 31562347 = 31562448
149 + 31562299 = 31562448
157 + 31562291 = 31562448
167 + 31562281 = 31562448

Showing the first eight; more decompositions exist.
