Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6590, here are decompositions:

13 + 6577 = 6590
19 + 6571 = 6590
37 + 6553 = 6590
43 + 6547 = 6590
61 + 6529 = 6590
109 + 6481 = 6590
139 + 6451 = 6590
163 + 6427 = 6590

Showing the first eight; more decompositions exist.
