Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12038, here are decompositions:
- 31 + 12007 = 12038
- 67 + 11971 = 12038
- 79 + 11959 = 12038
- 97 + 11941 = 12038
- 151 + 11887 = 12038
- 199 + 11839 = 12038
- 211 + 11827 = 12038
- 307 + 11731 = 12038
Showing the first eight; more decompositions exist.
