Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743902, here are decompositions:

19 + 8743883 = 8743902
23 + 8743879 = 8743902
59 + 8743843 = 8743902
131 + 8743771 = 8743902
149 + 8743753 = 8743902
191 + 8743711 = 8743902
229 + 8743673 = 8743902
263 + 8743639 = 8743902

Showing the first eight; more decompositions exist.
