Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722070, here are decompositions:

37 + 8722033 = 8722070
43 + 8722027 = 8722070
61 + 8722009 = 8722070
73 + 8721997 = 8722070
157 + 8721913 = 8722070
163 + 8721907 = 8722070
193 + 8721877 = 8722070
307 + 8721763 = 8722070

Showing the first eight; more decompositions exist.
