Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988418, here are decompositions:

61 + 988357 = 988418
97 + 988321 = 988418
139 + 988279 = 988418
181 + 988237 = 988418
199 + 988219 = 988418
271 + 988147 = 988418
307 + 988111 = 988418
349 + 988069 = 988418

Showing the first eight; more decompositions exist.
