Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488538, here are decompositions:

79 + 488459 = 488538
97 + 488441 = 488538
131 + 488407 = 488538
137 + 488401 = 488538
139 + 488399 = 488538
157 + 488381 = 488538
191 + 488347 = 488538
199 + 488339 = 488538

Showing the first eight; more decompositions exist.
