Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294961942, here are decompositions:
- 79 + 4294961863 = 4294961942
- 151 + 4294961791 = 4294961942
- 421 + 4294961521 = 4294961942
- 541 + 4294961401 = 4294961942
- 823 + 4294961119 = 4294961942
- 919 + 4294961023 = 4294961942
- 991 + 4294960951 = 4294961942
- 1381 + 4294960561 = 4294961942
Showing the first eight; more decompositions exist.
