Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488842, here are decompositions:

83 + 488759 = 488842
113 + 488729 = 488842
131 + 488711 = 488842
191 + 488651 = 488842
239 + 488603 = 488842
269 + 488573 = 488842
383 + 488459 = 488842
401 + 488441 = 488842

Showing the first eight; more decompositions exist.
