Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047132, here are decompositions:
- 5 + 1047127 = 1047132
- 13 + 1047119 = 1047132
- 43 + 1047089 = 1047132
- 71 + 1047061 = 1047132
- 89 + 1047043 = 1047132
- 101 + 1047031 = 1047132
- 139 + 1046993 = 1047132
- 173 + 1046959 = 1047132
Showing the first eight; more decompositions exist.
