Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742444, here are decompositions:

23 + 8742421 = 8742444
43 + 8742401 = 8742444
97 + 8742347 = 8742444
127 + 8742317 = 8742444
131 + 8742313 = 8742444
181 + 8742263 = 8742444
251 + 8742193 = 8742444
257 + 8742187 = 8742444

Showing the first eight; more decompositions exist.
