Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8662072, here are decompositions:

53 + 8662019 = 8662072
131 + 8661941 = 8662072
173 + 8661899 = 8662072
191 + 8661881 = 8662072
233 + 8661839 = 8662072
383 + 8661689 = 8662072
389 + 8661683 = 8662072
431 + 8661641 = 8662072

Showing the first eight; more decompositions exist.
