Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101580, here are decompositions:

7 + 101573 = 101580
19 + 101561 = 101580
43 + 101537 = 101580
47 + 101533 = 101580
53 + 101527 = 101580
67 + 101513 = 101580
79 + 101501 = 101580
97 + 101483 = 101580

Showing the first eight; more decompositions exist.
