Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025742, here are decompositions:

73 + 1025669 = 1025742
83 + 1025659 = 1025742
89 + 1025653 = 1025742
101 + 1025641 = 1025742
131 + 1025611 = 1025742
163 + 1025579 = 1025742
181 + 1025561 = 1025742
191 + 1025551 = 1025742

Showing the first eight; more decompositions exist.
