Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90438, here are decompositions:
- 31 + 90407 = 90438
- 37 + 90401 = 90438
- 41 + 90397 = 90438
- 59 + 90379 = 90438
- 67 + 90371 = 90438
- 79 + 90359 = 90438
- 149 + 90289 = 90438
- 157 + 90281 = 90438
Showing the first eight; more decompositions exist.
