Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487790, here are decompositions:

7 + 487783 = 487790
73 + 487717 = 487790
109 + 487681 = 487790
139 + 487651 = 487790
229 + 487561 = 487790
283 + 487507 = 487790
313 + 487477 = 487790
367 + 487423 = 487790

Showing the first eight; more decompositions exist.
