Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599232, here are decompositions:

59 + 31599173 = 31599232
131 + 31599101 = 31599232
173 + 31599059 = 31599232
293 + 31598939 = 31599232
359 + 31598873 = 31599232
443 + 31598789 = 31599232
449 + 31598783 = 31599232
461 + 31598771 = 31599232

Showing the first eight; more decompositions exist.
