Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87948, here are decompositions:
- 5 + 87943 = 87948
- 17 + 87931 = 87948
- 31 + 87917 = 87948
- 37 + 87911 = 87948
- 61 + 87887 = 87948
- 67 + 87881 = 87948
- 71 + 87877 = 87948
- 79 + 87869 = 87948
Showing the first eight; more decompositions exist.
