Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87202, here are decompositions:
- 23 + 87179 = 87202
- 53 + 87149 = 87202
- 83 + 87119 = 87202
- 131 + 87071 = 87202
- 191 + 87011 = 87202
- 233 + 86969 = 87202
- 251 + 86951 = 87202
- 263 + 86939 = 87202
Showing the first eight; more decompositions exist.
