Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988258, here are decompositions:

41 + 988217 = 988258
59 + 988199 = 988258
101 + 988157 = 988258
149 + 988109 = 988258
191 + 988067 = 988258
197 + 988061 = 988258
251 + 988007 = 988258
317 + 987941 = 988258

Showing the first eight; more decompositions exist.
