Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722148, here are decompositions:

31 + 8722117 = 8722148
67 + 8722081 = 8722148
139 + 8722009 = 8722148
151 + 8721997 = 8722148
241 + 8721907 = 8722148
271 + 8721877 = 8722148
541 + 8721607 = 8722148
607 + 8721541 = 8722148

Showing the first eight; more decompositions exist.
