Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460450, here are decompositions:

19 + 31460431 = 31460450
37 + 31460413 = 31460450
103 + 31460347 = 31460450
157 + 31460293 = 31460450
277 + 31460173 = 31460450
283 + 31460167 = 31460450
313 + 31460137 = 31460450
397 + 31460053 = 31460450

Showing the first eight; more decompositions exist.
