Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526442, here are decompositions:

13 + 526429 = 526442
19 + 526423 = 526442
61 + 526381 = 526442
151 + 526291 = 526442
193 + 526249 = 526442
211 + 526231 = 526442
229 + 526213 = 526442
283 + 526159 = 526442

Showing the first eight; more decompositions exist.
