Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87038, here are decompositions:
- 79 + 86959 = 87038
- 109 + 86929 = 87038
- 181 + 86857 = 87038
- 271 + 86767 = 87038
- 349 + 86689 = 87038
- 409 + 86629 = 87038
- 439 + 86599 = 87038
- 499 + 86539 = 87038
Showing the first eight; more decompositions exist.
