Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988550, here are decompositions:

61 + 988489 = 988550
67 + 988483 = 988550
97 + 988453 = 988550
193 + 988357 = 988550
229 + 988321 = 988550
271 + 988279 = 988550
307 + 988243 = 988550
313 + 988237 = 988550

Showing the first eight; more decompositions exist.
