Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488786, here are decompositions:

7 + 488779 = 488786
37 + 488749 = 488786
43 + 488743 = 488786
97 + 488689 = 488786
283 + 488503 = 488786
313 + 488473 = 488786
367 + 488419 = 488786
379 + 488407 = 488786

Showing the first eight; more decompositions exist.
