Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525742, here are decompositions:

3 + 525739 = 525742
11 + 525731 = 525742
23 + 525719 = 525742
29 + 525713 = 525742
71 + 525671 = 525742
101 + 525641 = 525742
149 + 525593 = 525742
251 + 525491 = 525742

Showing the first eight; more decompositions exist.
