Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 972900, here are decompositions:
- 13 + 972887 = 972900
- 31 + 972869 = 972900
- 53 + 972847 = 972900
- 67 + 972833 = 972900
- 73 + 972827 = 972900
- 101 + 972799 = 972900
- 107 + 972793 = 972900
- 113 + 972787 = 972900
Showing the first eight; more decompositions exist.
