Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1038578, here are decompositions:

157 + 1038421 = 1038578
241 + 1038337 = 1038578
271 + 1038307 = 1038578
367 + 1038211 = 1038578
379 + 1038199 = 1038578
421 + 1038157 = 1038578
577 + 1038001 = 1038578
661 + 1037917 = 1038578

Showing the first eight; more decompositions exist.
