Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 942978, here are decompositions:
- 61 + 942917 = 942978
- 79 + 942899 = 942978
- 89 + 942889 = 942978
- 109 + 942869 = 942978
- 131 + 942847 = 942978
- 151 + 942827 = 942978
- 167 + 942811 = 942978
- 191 + 942787 = 942978
Showing the first eight; more decompositions exist.
