Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158404, here are decompositions:

11 + 158393 = 158404
41 + 158363 = 158404
47 + 158357 = 158404
53 + 158351 = 158404
101 + 158303 = 158404
173 + 158231 = 158404
263 + 158141 = 158404
401 + 158003 = 158404

Showing the first eight; more decompositions exist.
