Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997386, here are decompositions:
- 7 + 997379 = 997386
- 17 + 997369 = 997386
- 29 + 997357 = 997386
- 43 + 997343 = 997386
- 53 + 997333 = 997386
- 59 + 997327 = 997386
- 67 + 997319 = 997386
- 79 + 997307 = 997386
Showing the first eight; more decompositions exist.
