Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598142, here are decompositions:

5 + 31598137 = 31598142
41 + 31598101 = 31598142
109 + 31598033 = 31598142
113 + 31598029 = 31598142
131 + 31598011 = 31598142
181 + 31597961 = 31598142
229 + 31597913 = 31598142
263 + 31597879 = 31598142

Showing the first eight; more decompositions exist.
