Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601264, here are decompositions:

61 + 31601203 = 31601264
73 + 31601191 = 31601264
127 + 31601137 = 31601264
181 + 31601083 = 31601264
223 + 31601041 = 31601264
241 + 31601023 = 31601264
271 + 31600993 = 31601264
307 + 31600957 = 31601264

Showing the first eight; more decompositions exist.
