Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 972786, here are decompositions:

103 + 972683 = 972786
107 + 972679 = 972786
137 + 972649 = 972786
149 + 972637 = 972786
163 + 972623 = 972786
173 + 972613 = 972786
229 + 972557 = 972786
293 + 972493 = 972786

Showing the first eight; more decompositions exist.
