Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601292, here are decompositions:

29 + 31601263 = 31601292
89 + 31601203 = 31601292
101 + 31601191 = 31601292
113 + 31601179 = 31601292
193 + 31601099 = 31601292
241 + 31601051 = 31601292
251 + 31601041 = 31601292
269 + 31601023 = 31601292

Showing the first eight; more decompositions exist.
