Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72836, here are decompositions:
- 13 + 72823 = 72836
- 19 + 72817 = 72836
- 73 + 72763 = 72836
- 97 + 72739 = 72836
- 103 + 72733 = 72836
- 109 + 72727 = 72836
- 157 + 72679 = 72836
- 163 + 72673 = 72836
Showing the first eight; more decompositions exist.
