Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742626, here are decompositions:

3 + 8742623 = 8742626
97 + 8742529 = 8742626
127 + 8742499 = 8742626
157 + 8742469 = 8742626
163 + 8742463 = 8742626
313 + 8742313 = 8742626
367 + 8742259 = 8742626
433 + 8742193 = 8742626

Showing the first eight; more decompositions exist.
