Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737428, here are decompositions:
- 5 + 8737423 = 8737428
- 71 + 8737357 = 8737428
- 79 + 8737349 = 8737428
- 127 + 8737301 = 8737428
- 151 + 8737277 = 8737428
- 157 + 8737271 = 8737428
- 179 + 8737249 = 8737428
- 181 + 8737247 = 8737428
Showing the first eight; more decompositions exist.
