Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8612840, here are decompositions:

3 + 8612837 = 8612840
73 + 8612767 = 8612840
97 + 8612743 = 8612840
109 + 8612731 = 8612840
127 + 8612713 = 8612840
139 + 8612701 = 8612840
151 + 8612689 = 8612840
157 + 8612683 = 8612840

Showing the first eight; more decompositions exist.
