Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743892, here are decompositions:

13 + 8743879 = 8743892
139 + 8743753 = 8743892
181 + 8743711 = 8743892
211 + 8743681 = 8743892
271 + 8743621 = 8743892
331 + 8743561 = 8743892
379 + 8743513 = 8743892
433 + 8743459 = 8743892

Showing the first eight; more decompositions exist.
