Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64942, here are decompositions:
- 5 + 64937 = 64942
- 23 + 64919 = 64942
- 41 + 64901 = 64942
- 71 + 64871 = 64942
- 89 + 64853 = 64942
- 131 + 64811 = 64942
- 149 + 64793 = 64942
- 179 + 64763 = 64942
Showing the first eight; more decompositions exist.
