Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1007990, here are decompositions:
- 13 + 1007977 = 1007990
- 19 + 1007971 = 1007990
- 31 + 1007959 = 1007990
- 103 + 1007887 = 1007990
- 163 + 1007827 = 1007990
- 223 + 1007767 = 1007990
- 241 + 1007749 = 1007990
- 271 + 1007719 = 1007990
Showing the first eight; more decompositions exist.
