Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73990, here are decompositions:
- 17 + 73973 = 73990
- 29 + 73961 = 73990
- 47 + 73943 = 73990
- 83 + 73907 = 73990
- 107 + 73883 = 73990
- 113 + 73877 = 73990
- 131 + 73859 = 73990
- 167 + 73823 = 73990
Showing the first eight; more decompositions exist.
