Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989156, here are decompositions:

37 + 989119 = 989156
97 + 989059 = 989156
127 + 989029 = 989156
193 + 988963 = 989156
307 + 988849 = 989156
367 + 988789 = 989156
373 + 988783 = 989156
397 + 988759 = 989156

Showing the first eight; more decompositions exist.
