Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526792, here are decompositions:
- 19 + 31526773 = 31526792
- 43 + 31526749 = 31526792
- 61 + 31526731 = 31526792
- 79 + 31526713 = 31526792
- 103 + 31526689 = 31526792
- 229 + 31526563 = 31526792
- 373 + 31526419 = 31526792
- 421 + 31526371 = 31526792
Showing the first eight; more decompositions exist.
