Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1007578, here are decompositions:

29 + 1007549 = 1007578
59 + 1007519 = 1007578
137 + 1007441 = 1007578
149 + 1007429 = 1007578
191 + 1007387 = 1007578
197 + 1007381 = 1007578
239 + 1007339 = 1007578
269 + 1007309 = 1007578

Showing the first eight; more decompositions exist.
