Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748538, here are decompositions:

107 + 8748431 = 8748538
179 + 8748359 = 8748538
251 + 8748287 = 8748538
257 + 8748281 = 8748538
347 + 8748191 = 8748538
401 + 8748137 = 8748538
521 + 8748017 = 8748538
647 + 8747891 = 8748538

Showing the first eight; more decompositions exist.
