Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981360, here are decompositions:
- 41 + 981319 = 981360
- 59 + 981301 = 981360
- 71 + 981289 = 981360
- 73 + 981287 = 981360
- 89 + 981271 = 981360
- 97 + 981263 = 981360
- 139 + 981221 = 981360
- 151 + 981209 = 981360
Showing the first eight; more decompositions exist.
