Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 88390, here are decompositions:
- 11 + 88379 = 88390
- 53 + 88337 = 88390
- 89 + 88301 = 88390
- 101 + 88289 = 88390
- 131 + 88259 = 88390
- 149 + 88241 = 88390
- 167 + 88223 = 88390
- 179 + 88211 = 88390
Showing the first eight; more decompositions exist.
