Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1011398, here are decompositions:

7 + 1011391 = 1011398
67 + 1011331 = 1011398
109 + 1011289 = 1011398
127 + 1011271 = 1011398
181 + 1011217 = 1011398
307 + 1011091 = 1011398
331 + 1011067 = 1011398
397 + 1011001 = 1011398

Showing the first eight; more decompositions exist.
