Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87758, here are decompositions:
- 7 + 87751 = 87758
- 19 + 87739 = 87758
- 37 + 87721 = 87758
- 61 + 87697 = 87758
- 67 + 87691 = 87758
- 79 + 87679 = 87758
- 109 + 87649 = 87758
- 127 + 87631 = 87758
Showing the first eight; more decompositions exist.
