Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1007438, here are decompositions:
- 37 + 1007401 = 1007438
- 79 + 1007359 = 1007438
- 139 + 1007299 = 1007438
- 277 + 1007161 = 1007438
- 349 + 1007089 = 1007438
- 379 + 1007059 = 1007438
- 541 + 1006897 = 1007438
- 547 + 1006891 = 1007438
Showing the first eight; more decompositions exist.
