Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 70872, here are decompositions:
- 5 + 70867 = 70872
- 19 + 70853 = 70872
- 23 + 70849 = 70872
- 29 + 70843 = 70872
- 31 + 70841 = 70872
- 79 + 70793 = 70872
- 89 + 70783 = 70872
- 103 + 70769 = 70872
Showing the first eight; more decompositions exist.
