Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525770, here are decompositions:

31 + 525739 = 525770
43 + 525727 = 525770
61 + 525709 = 525770
73 + 525697 = 525770
163 + 525607 = 525770
199 + 525571 = 525770
229 + 525541 = 525770
241 + 525529 = 525770

Showing the first eight; more decompositions exist.
