Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599202, here are decompositions:

29 + 31599173 = 31599202
101 + 31599101 = 31599202
263 + 31598939 = 31599202
269 + 31598933 = 31599202
293 + 31598909 = 31599202
419 + 31598783 = 31599202
431 + 31598771 = 31599202
449 + 31598753 = 31599202

Showing the first eight; more decompositions exist.
