Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142004, here are decompositions:

13 + 141991 = 142004
43 + 141961 = 142004
67 + 141937 = 142004
73 + 141931 = 142004
97 + 141907 = 142004
151 + 141853 = 142004
193 + 141811 = 142004
211 + 141793 = 142004

Showing the first eight; more decompositions exist.
