Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469760, here are decompositions:
- 19 + 31469741 = 31469760
- 29 + 31469731 = 31469760
- 37 + 31469723 = 31469760
- 71 + 31469689 = 31469760
- 89 + 31469671 = 31469760
- 107 + 31469653 = 31469760
- 131 + 31469629 = 31469760
- 137 + 31469623 = 31469760
Showing the first eight; more decompositions exist.
