Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100672, here are decompositions:

3 + 100669 = 100672
23 + 100649 = 100672
59 + 100613 = 100672
113 + 100559 = 100672
149 + 100523 = 100672
179 + 100493 = 100672
269 + 100403 = 100672
281 + 100391 = 100672

Showing the first eight; more decompositions exist.
