Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525572, here are decompositions:

31 + 525541 = 525572
43 + 525529 = 525572
79 + 525493 = 525572
139 + 525433 = 525572
163 + 525409 = 525572
181 + 525391 = 525572
193 + 525379 = 525572
199 + 525373 = 525572

Showing the first eight; more decompositions exist.
