Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599226, here are decompositions:

53 + 31599173 = 31599226
167 + 31599059 = 31599226
293 + 31598933 = 31599226
317 + 31598909 = 31599226
353 + 31598873 = 31599226
359 + 31598867 = 31599226
443 + 31598783 = 31599226
509 + 31598717 = 31599226

Showing the first eight; more decompositions exist.
