Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751398, here are decompositions:

31 + 8751367 = 8751398
79 + 8751319 = 8751398
109 + 8751289 = 8751398
241 + 8751157 = 8751398
307 + 8751091 = 8751398
457 + 8750941 = 8751398
541 + 8750857 = 8751398
661 + 8750737 = 8751398

Showing the first eight; more decompositions exist.
