Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 972930, here are decompositions:
- 29 + 972901 = 972930
- 31 + 972899 = 972930
- 43 + 972887 = 972930
- 61 + 972869 = 972930
- 83 + 972847 = 972930
- 97 + 972833 = 972930
- 103 + 972827 = 972930
- 107 + 972823 = 972930
Showing the first eight; more decompositions exist.
