Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 129004, here are decompositions:

3 + 129001 = 129004
11 + 128993 = 129004
17 + 128987 = 129004
23 + 128981 = 129004
53 + 128951 = 129004
101 + 128903 = 129004
131 + 128873 = 129004
167 + 128837 = 129004

Showing the first eight; more decompositions exist.
