Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987672, here are decompositions:

13 + 987659 = 987672
41 + 987631 = 987672
73 + 987599 = 987672
79 + 987593 = 987672
113 + 987559 = 987672
131 + 987541 = 987672
139 + 987533 = 987672
149 + 987523 = 987672

Showing the first eight; more decompositions exist.
