Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530792, here are decompositions:
- 19 + 31530773 = 31530792
- 79 + 31530713 = 31530792
- 89 + 31530703 = 31530792
- 109 + 31530683 = 31530792
- 113 + 31530679 = 31530792
- 131 + 31530661 = 31530792
- 149 + 31530643 = 31530792
- 151 + 31530641 = 31530792
Showing the first eight; more decompositions exist.
