Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45872, here are decompositions:
- 3 + 45869 = 45872
- 19 + 45853 = 45872
- 31 + 45841 = 45872
- 109 + 45763 = 45872
- 181 + 45691 = 45872
- 199 + 45673 = 45872
- 241 + 45631 = 45872
- 283 + 45589 = 45872
Showing the first eight; more decompositions exist.
