Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490972, here are decompositions:

3 + 490969 = 490972
5 + 490967 = 490972
23 + 490949 = 490972
59 + 490913 = 490972
113 + 490859 = 490972
239 + 490733 = 490972
311 + 490661 = 490972
353 + 490619 = 490972

Showing the first eight; more decompositions exist.
