Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987148, here are decompositions:

5 + 987143 = 987148
47 + 987101 = 987148
59 + 987089 = 987148
167 + 986981 = 987148
311 + 986837 = 987148
347 + 986801 = 987148
389 + 986759 = 987148
419 + 986729 = 987148

Showing the first eight; more decompositions exist.
