Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987360, here are decompositions:
- 7 + 987353 = 987360
- 47 + 987313 = 987360
- 61 + 987299 = 987360
- 67 + 987293 = 987360
- 109 + 987251 = 987360
- 149 + 987211 = 987360
- 151 + 987209 = 987360
- 167 + 987193 = 987360
Showing the first eight; more decompositions exist.
