Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71802, here are decompositions:
- 13 + 71789 = 71802
- 41 + 71761 = 71802
- 61 + 71741 = 71802
- 83 + 71719 = 71802
- 89 + 71713 = 71802
- 103 + 71699 = 71802
- 109 + 71693 = 71802
- 131 + 71671 = 71802
Showing the first eight; more decompositions exist.
