Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988278, here are decompositions:

7 + 988271 = 988278
41 + 988237 = 988278
47 + 988231 = 988278
59 + 988219 = 988278
61 + 988217 = 988278
79 + 988199 = 988278
131 + 988147 = 988278
149 + 988129 = 988278

Showing the first eight; more decompositions exist.
