Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672138, here are decompositions:
- 37 + 8672101 = 8672138
- 151 + 8671987 = 8672138
- 157 + 8671981 = 8672138
- 499 + 8671639 = 8672138
- 619 + 8671519 = 8672138
- 691 + 8671447 = 8672138
- 757 + 8671381 = 8672138
- 907 + 8671231 = 8672138
Showing the first eight; more decompositions exist.
