Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90278, here are decompositions:
- 7 + 90271 = 90278
- 31 + 90247 = 90278
- 61 + 90217 = 90278
- 79 + 90199 = 90278
- 151 + 90127 = 90278
- 157 + 90121 = 90278
- 211 + 90067 = 90278
- 271 + 90007 = 90278
Showing the first eight; more decompositions exist.
