Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987174, here are decompositions:

31 + 987143 = 987174
47 + 987127 = 987174
73 + 987101 = 987174
107 + 987067 = 987174
113 + 987061 = 987174
131 + 987043 = 987174
151 + 987023 = 987174
191 + 986983 = 987174

Showing the first eight; more decompositions exist.
