Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61878, here are decompositions:
- 7 + 61871 = 61878
- 17 + 61861 = 61878
- 41 + 61837 = 61878
- 59 + 61819 = 61878
- 97 + 61781 = 61878
- 127 + 61751 = 61878
- 149 + 61729 = 61878
- 191 + 61687 = 61878
Showing the first eight; more decompositions exist.
