Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543722, here are decompositions:
- 11 + 31543711 = 31543722
- 31 + 31543691 = 31543722
- 53 + 31543669 = 31543722
- 61 + 31543661 = 31543722
- 79 + 31543643 = 31543722
- 151 + 31543571 = 31543722
- 179 + 31543543 = 31543722
- 191 + 31543531 = 31543722
Showing the first eight; more decompositions exist.
