Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601318, here are decompositions:

127 + 31601191 = 31601318
139 + 31601179 = 31601318
181 + 31601137 = 31601318
241 + 31601077 = 31601318
277 + 31601041 = 31601318
349 + 31600969 = 31601318
457 + 31600861 = 31601318
547 + 31600771 = 31601318

Showing the first eight; more decompositions exist.
