Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 972778, here are decompositions:

167 + 972611 = 972778
179 + 972599 = 972778
197 + 972581 = 972778
347 + 972431 = 972778
431 + 972347 = 972778
449 + 972329 = 972778
557 + 972221 = 972778
617 + 972161 = 972778

Showing the first eight; more decompositions exist.
