Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599004, here are decompositions:

71 + 31598933 = 31599004
131 + 31598873 = 31599004
137 + 31598867 = 31599004
233 + 31598771 = 31599004
251 + 31598753 = 31599004
317 + 31598687 = 31599004
461 + 31598543 = 31599004
467 + 31598537 = 31599004

Showing the first eight; more decompositions exist.
