Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294976988, here are decompositions:
- 7 + 4294976981 = 4294976988
- 11 + 4294976977 = 4294976988
- 31 + 4294976957 = 4294976988
- 47 + 4294976941 = 4294976988
- 59 + 4294976929 = 4294976988
- 101 + 4294976887 = 4294976988
- 131 + 4294976857 = 4294976988
- 149 + 4294976839 = 4294976988
Showing the first eight; more decompositions exist.
