Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738442, here are decompositions:
- 5 + 8738437 = 8738442
- 43 + 8738399 = 8738442
- 59 + 8738383 = 8738442
- 79 + 8738363 = 8738442
- 103 + 8738339 = 8738442
- 109 + 8738333 = 8738442
- 149 + 8738293 = 8738442
- 179 + 8738263 = 8738442
Showing the first eight; more decompositions exist.
