Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157590, here are decompositions:

11 + 157579 = 157590
19 + 157571 = 157590
29 + 157561 = 157590
31 + 157559 = 157590
47 + 157543 = 157590
67 + 157523 = 157590
71 + 157519 = 157590
101 + 157489 = 157590

Showing the first eight; more decompositions exist.
