Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 88040, here are decompositions:
- 3 + 88037 = 88040
- 37 + 88003 = 88040
- 67 + 87973 = 88040
- 79 + 87961 = 88040
- 97 + 87943 = 88040
- 109 + 87931 = 88040
- 163 + 87877 = 88040
- 229 + 87811 = 88040
Showing the first eight; more decompositions exist.
