Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747948, here are decompositions:

7 + 8747941 = 8747948
19 + 8747929 = 8747948
31 + 8747917 = 8747948
211 + 8747737 = 8747948
271 + 8747677 = 8747948
331 + 8747617 = 8747948
409 + 8747539 = 8747948
421 + 8747527 = 8747948

Showing the first eight; more decompositions exist.
