Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599028, here are decompositions:

89 + 31598939 = 31599028
101 + 31598927 = 31599028
239 + 31598789 = 31599028
257 + 31598771 = 31599028
311 + 31598717 = 31599028
359 + 31598669 = 31599028
491 + 31598537 = 31599028
509 + 31598519 = 31599028

Showing the first eight; more decompositions exist.
