Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19542, here are decompositions:

11 + 19531 = 19542
41 + 19501 = 19542
53 + 19489 = 19542
59 + 19483 = 19542
71 + 19471 = 19542
73 + 19469 = 19542
79 + 19463 = 19542
101 + 19441 = 19542

Showing the first eight; more decompositions exist.
