Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526844, here are decompositions:

53 + 31526791 = 31526844
67 + 31526777 = 31526844
71 + 31526773 = 31526844
73 + 31526771 = 31526844
113 + 31526731 = 31526844
131 + 31526713 = 31526844
197 + 31526647 = 31526844
211 + 31526633 = 31526844

Showing the first eight; more decompositions exist.
