Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025650, here are decompositions:

29 + 1025621 = 1025650
71 + 1025579 = 1025650
89 + 1025561 = 1025650
107 + 1025543 = 1025650
113 + 1025537 = 1025650
137 + 1025513 = 1025650
167 + 1025483 = 1025650
173 + 1025477 = 1025650

Showing the first eight; more decompositions exist.
