Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139626, here are decompositions:

7 + 139619 = 139626
17 + 139609 = 139626
29 + 139597 = 139626
37 + 139589 = 139626
79 + 139547 = 139626
89 + 139537 = 139626
139 + 139487 = 139626
167 + 139459 = 139626

Showing the first eight; more decompositions exist.
