Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525002, here are decompositions:

3 + 524999 = 525002
19 + 524983 = 525002
31 + 524971 = 525002
43 + 524959 = 525002
61 + 524941 = 525002
103 + 524899 = 525002
109 + 524893 = 525002
139 + 524863 = 525002

Showing the first eight; more decompositions exist.
