Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 972738, here are decompositions:

17 + 972721 = 972738
37 + 972701 = 972738
59 + 972679 = 972738
89 + 972649 = 972738
101 + 972637 = 972738
127 + 972611 = 972738
139 + 972599 = 972738
157 + 972581 = 972738

Showing the first eight; more decompositions exist.
