Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598072, here are decompositions:

43 + 31598029 = 31598072
61 + 31598011 = 31598072
139 + 31597933 = 31598072
193 + 31597879 = 31598072
199 + 31597873 = 31598072
229 + 31597843 = 31598072
271 + 31597801 = 31598072
379 + 31597693 = 31598072

Showing the first eight; more decompositions exist.
