Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64872, here are decompositions:
- 19 + 64853 = 64872
- 23 + 64849 = 64872
- 61 + 64811 = 64872
- 79 + 64793 = 64872
- 89 + 64783 = 64872
- 109 + 64763 = 64872
- 163 + 64709 = 64872
- 179 + 64693 = 64872
Showing the first eight; more decompositions exist.
