Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525590, here are decompositions:

7 + 525583 = 525590
19 + 525571 = 525590
61 + 525529 = 525590
73 + 525517 = 525590
97 + 525493 = 525590
151 + 525439 = 525590
157 + 525433 = 525590
181 + 525409 = 525590

Showing the first eight; more decompositions exist.
