Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601276, here are decompositions:

13 + 31601263 = 31601276
73 + 31601203 = 31601276
97 + 31601179 = 31601276
139 + 31601137 = 31601276
193 + 31601083 = 31601276
199 + 31601077 = 31601276
283 + 31600993 = 31601276
307 + 31600969 = 31601276

Showing the first eight; more decompositions exist.
