Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61884, here are decompositions:
- 5 + 61879 = 61884
- 13 + 61871 = 61884
- 23 + 61861 = 61884
- 41 + 61843 = 61884
- 47 + 61837 = 61884
- 71 + 61813 = 61884
- 103 + 61781 = 61884
- 127 + 61757 = 61884
Showing the first eight; more decompositions exist.
