Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 527242, here are decompositions:

5 + 527237 = 527242
83 + 527159 = 527242
113 + 527129 = 527242
173 + 527069 = 527242
179 + 527063 = 527242
311 + 526931 = 527242
383 + 526859 = 527242
389 + 526853 = 527242

Showing the first eight; more decompositions exist.
