Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749456, here are decompositions:

5 + 8749451 = 8749456
17 + 8749439 = 8749456
113 + 8749343 = 8749456
227 + 8749229 = 8749456
257 + 8749199 = 8749456
293 + 8749163 = 8749456
449 + 8749007 = 8749456
467 + 8748989 = 8749456

Showing the first eight; more decompositions exist.
