Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 971778, here are decompositions:
- 11 + 971767 = 971778
- 19 + 971759 = 971778
- 79 + 971699 = 971778
- 127 + 971651 = 971778
- 139 + 971639 = 971778
- 229 + 971549 = 971778
- 257 + 971521 = 971778
- 277 + 971501 = 971778
Showing the first eight; more decompositions exist.
