Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61908, here are decompositions:
- 29 + 61879 = 61908
- 37 + 61871 = 61908
- 47 + 61861 = 61908
- 71 + 61837 = 61908
- 89 + 61819 = 61908
- 127 + 61781 = 61908
- 151 + 61757 = 61908
- 157 + 61751 = 61908
Showing the first eight; more decompositions exist.
