Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678040, here are decompositions:
- 11 + 8678029 = 8678040
- 13 + 8678027 = 8678040
- 29 + 8678011 = 8678040
- 47 + 8677993 = 8678040
- 61 + 8677979 = 8678040
- 73 + 8677967 = 8678040
- 79 + 8677961 = 8678040
- 89 + 8677951 = 8678040
Showing the first eight; more decompositions exist.
