Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45712, here are decompositions:
- 5 + 45707 = 45712
- 53 + 45659 = 45712
- 71 + 45641 = 45712
- 113 + 45599 = 45712
- 179 + 45533 = 45712
- 383 + 45329 = 45712
- 419 + 45293 = 45712
- 431 + 45281 = 45712
Showing the first eight; more decompositions exist.
