Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61872, here are decompositions:
- 11 + 61861 = 61872
- 29 + 61843 = 61872
- 53 + 61819 = 61872
- 59 + 61813 = 61872
- 149 + 61723 = 61872
- 191 + 61681 = 61872
- 199 + 61673 = 61872
- 229 + 61643 = 61872
Showing the first eight; more decompositions exist.
