Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8750742, here are decompositions:
- 5 + 8750737 = 8750742
- 23 + 8750719 = 8750742
- 29 + 8750713 = 8750742
- 41 + 8750701 = 8750742
- 53 + 8750689 = 8750742
- 101 + 8750641 = 8750742
- 103 + 8750639 = 8750742
- 151 + 8750591 = 8750742
Showing the first eight; more decompositions exist.
