Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988318, here are decompositions:

5 + 988313 = 988318
47 + 988271 = 988318
101 + 988217 = 988318
251 + 988067 = 988318
257 + 988061 = 988318
311 + 988007 = 988318
347 + 987971 = 988318
389 + 987929 = 988318

Showing the first eight; more decompositions exist.
