Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601330, here are decompositions:

67 + 31601263 = 31601330
127 + 31601203 = 31601330
139 + 31601191 = 31601330
151 + 31601179 = 31601330
193 + 31601137 = 31601330
307 + 31601023 = 31601330
337 + 31600993 = 31601330
373 + 31600957 = 31601330

Showing the first eight; more decompositions exist.
