Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025698, here are decompositions:

5 + 1025693 = 1025698
29 + 1025669 = 1025698
137 + 1025561 = 1025698
239 + 1025459 = 1025698
281 + 1025417 = 1025698
347 + 1025351 = 1025698
419 + 1025279 = 1025698
431 + 1025267 = 1025698

Showing the first eight; more decompositions exist.
