Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478874, here are decompositions:
- 3 + 478871 = 478874
- 13 + 478861 = 478874
- 31 + 478843 = 478874
- 43 + 478831 = 478874
- 61 + 478813 = 478874
- 73 + 478801 = 478874
- 127 + 478747 = 478874
- 163 + 478711 = 478874
Showing the first eight; more decompositions exist.
