Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738772, here are decompositions:

5 + 8738767 = 8738772
13 + 8738759 = 8738772
43 + 8738729 = 8738772
59 + 8738713 = 8738772
61 + 8738711 = 8738772
101 + 8738671 = 8738772
113 + 8738659 = 8738772
131 + 8738641 = 8738772

Showing the first eight; more decompositions exist.
