Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672490, here are decompositions:

7 + 8672483 = 8672490
19 + 8672471 = 8672490
61 + 8672429 = 8672490
67 + 8672423 = 8672490
83 + 8672407 = 8672490
103 + 8672387 = 8672490
109 + 8672381 = 8672490
137 + 8672353 = 8672490

Showing the first eight; more decompositions exist.
