Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87248, here are decompositions:
- 37 + 87211 = 87248
- 61 + 87187 = 87248
- 67 + 87181 = 87248
- 97 + 87151 = 87248
- 127 + 87121 = 87248
- 199 + 87049 = 87248
- 211 + 87037 = 87248
- 379 + 86869 = 87248
Showing the first eight; more decompositions exist.
