Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465426, here are decompositions:
- 137 + 31465289 = 31465426
- 233 + 31465193 = 31465426
- 479 + 31464947 = 31465426
- 599 + 31464827 = 31465426
- 617 + 31464809 = 31465426
- 809 + 31464617 = 31465426
- 983 + 31464443 = 31465426
- 1193 + 31464233 = 31465426
Showing the first eight; more decompositions exist.
