Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87284, here are decompositions:
- 3 + 87281 = 87284
- 7 + 87277 = 87284
- 31 + 87253 = 87284
- 61 + 87223 = 87284
- 73 + 87211 = 87284
- 97 + 87187 = 87284
- 103 + 87181 = 87284
- 151 + 87133 = 87284
Showing the first eight; more decompositions exist.
