Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126590, here are decompositions:

7 + 126583 = 126590
43 + 126547 = 126590
73 + 126517 = 126590
97 + 126493 = 126590
103 + 126487 = 126590
109 + 126481 = 126590
157 + 126433 = 126590
193 + 126397 = 126590

Showing the first eight; more decompositions exist.
