Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20672, here are decompositions:
- 31 + 20641 = 20672
- 61 + 20611 = 20672
- 73 + 20599 = 20672
- 79 + 20593 = 20672
- 109 + 20563 = 20672
- 139 + 20533 = 20672
- 151 + 20521 = 20672
- 163 + 20509 = 20672
Showing the first eight; more decompositions exist.
