Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51948, here are decompositions:
- 7 + 51941 = 51948
- 19 + 51929 = 51948
- 41 + 51907 = 51948
- 79 + 51869 = 51948
- 89 + 51859 = 51948
- 109 + 51839 = 51948
- 131 + 51817 = 51948
- 151 + 51797 = 51948
Showing the first eight; more decompositions exist.
