Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722318, here are decompositions:

107 + 8722211 = 8722318
131 + 8722187 = 8722318
149 + 8722169 = 8722318
239 + 8722079 = 8722318
317 + 8722001 = 8722318
389 + 8721929 = 8722318
401 + 8721917 = 8722318
467 + 8721851 = 8722318

Showing the first eight; more decompositions exist.
