Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489792, here are decompositions:
- 31 + 489761 = 489792
- 59 + 489733 = 489792
- 101 + 489691 = 489792
- 103 + 489689 = 489792
- 113 + 489679 = 489792
- 139 + 489653 = 489792
- 179 + 489613 = 489792
- 239 + 489553 = 489792
Showing the first eight; more decompositions exist.
