Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601234, here are decompositions:

31 + 31601203 = 31601234
43 + 31601191 = 31601234
97 + 31601137 = 31601234
151 + 31601083 = 31601234
157 + 31601077 = 31601234
193 + 31601041 = 31601234
211 + 31601023 = 31601234
241 + 31600993 = 31601234

Showing the first eight; more decompositions exist.
