Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526448, here are decompositions:

7 + 526441 = 526448
19 + 526429 = 526448
61 + 526387 = 526448
67 + 526381 = 526448
151 + 526297 = 526448
157 + 526291 = 526448
199 + 526249 = 526448
331 + 526117 = 526448

Showing the first eight; more decompositions exist.
