Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526580, here are decompositions:

7 + 526573 = 526580
37 + 526543 = 526580
79 + 526501 = 526580
97 + 526483 = 526580
127 + 526453 = 526580
139 + 526441 = 526580
151 + 526429 = 526580
157 + 526423 = 526580

Showing the first eight; more decompositions exist.
