Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981348, here are decompositions:

29 + 981319 = 981348
37 + 981311 = 981348
47 + 981301 = 981348
59 + 981289 = 981348
61 + 981287 = 981348
107 + 981241 = 981348
127 + 981221 = 981348
139 + 981209 = 981348

Showing the first eight; more decompositions exist.
