Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747946, here are decompositions:
- 5 + 8747941 = 8747946
- 13 + 8747933 = 8747946
- 17 + 8747929 = 8747946
- 19 + 8747927 = 8747946
- 29 + 8747917 = 8747946
- 43 + 8747903 = 8747946
- 83 + 8747863 = 8747946
- 89 + 8747857 = 8747946
Showing the first eight; more decompositions exist.
