Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488078, here are decompositions:

67 + 488011 = 488078
181 + 487897 = 488078
337 + 487741 = 488078
397 + 487681 = 488078
421 + 487657 = 488078
571 + 487507 = 488078
601 + 487477 = 488078
607 + 487471 = 488078

Showing the first eight; more decompositions exist.
