Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042500, here are decompositions:

13 + 1042487 = 1042500
31 + 1042469 = 1042500
61 + 1042439 = 1042500
73 + 1042427 = 1042500
101 + 1042399 = 1042500
127 + 1042373 = 1042500
131 + 1042369 = 1042500
167 + 1042333 = 1042500

Showing the first eight; more decompositions exist.
