Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 160542, here are decompositions:

43 + 160499 = 160542
59 + 160483 = 160542
61 + 160481 = 160542
89 + 160453 = 160542
101 + 160441 = 160542
139 + 160403 = 160542
199 + 160343 = 160542
223 + 160319 = 160542

Showing the first eight; more decompositions exist.
