Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025722, here are decompositions:

29 + 1025693 = 1025722
53 + 1025669 = 1025722
101 + 1025621 = 1025722
179 + 1025543 = 1025722
239 + 1025483 = 1025722
263 + 1025459 = 1025722
389 + 1025333 = 1025722
419 + 1025303 = 1025722

Showing the first eight; more decompositions exist.
