Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131562, here are decompositions:

19 + 131543 = 131562
43 + 131519 = 131562
61 + 131501 = 131562
73 + 131489 = 131562
83 + 131479 = 131562
113 + 131449 = 131562
131 + 131431 = 131562
149 + 131413 = 131562

Showing the first eight; more decompositions exist.
