Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601150, here are decompositions:

13 + 31601137 = 31601150
67 + 31601083 = 31601150
73 + 31601077 = 31601150
109 + 31601041 = 31601150
127 + 31601023 = 31601150
157 + 31600993 = 31601150
181 + 31600969 = 31601150
193 + 31600957 = 31601150

Showing the first eight; more decompositions exist.
