Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988390, here are decompositions:

23 + 988367 = 988390
47 + 988343 = 988390
71 + 988319 = 988390
173 + 988217 = 988390
191 + 988199 = 988390
233 + 988157 = 988390
281 + 988109 = 988390
383 + 988007 = 988390

Showing the first eight; more decompositions exist.
