Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87930, here are decompositions:
- 13 + 87917 = 87930
- 19 + 87911 = 87930
- 43 + 87887 = 87930
- 53 + 87877 = 87930
- 61 + 87869 = 87930
- 97 + 87833 = 87930
- 127 + 87803 = 87930
- 137 + 87793 = 87930
Showing the first eight; more decompositions exist.
