Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987132, here are decompositions:
- 5 + 987127 = 987132
- 31 + 987101 = 987132
- 43 + 987089 = 987132
- 53 + 987079 = 987132
- 71 + 987061 = 987132
- 79 + 987053 = 987132
- 89 + 987043 = 987132
- 103 + 987029 = 987132
Showing the first eight; more decompositions exist.
