Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130542, here are decompositions:

11 + 130531 = 130542
19 + 130523 = 130542
29 + 130513 = 130542
53 + 130489 = 130542
59 + 130483 = 130542
73 + 130469 = 130542
103 + 130439 = 130542
131 + 130411 = 130542

Showing the first eight; more decompositions exist.
