Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526430, here are decompositions:

7 + 526423 = 526430
43 + 526387 = 526430
139 + 526291 = 526430
181 + 526249 = 526430
199 + 526231 = 526430
241 + 526189 = 526430
271 + 526159 = 526430
313 + 526117 = 526430

Showing the first eight; more decompositions exist.
