Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460576, here are decompositions:

67 + 31460509 = 31460576
79 + 31460497 = 31460576
163 + 31460413 = 31460576
229 + 31460347 = 31460576
283 + 31460293 = 31460576
313 + 31460263 = 31460576
379 + 31460197 = 31460576
409 + 31460167 = 31460576

Showing the first eight; more decompositions exist.
