Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988378, here are decompositions:

11 + 988367 = 988378
59 + 988319 = 988378
107 + 988271 = 988378
179 + 988199 = 988378
269 + 988109 = 988378
311 + 988067 = 988378
317 + 988061 = 988378
449 + 987929 = 988378

Showing the first eight; more decompositions exist.
