Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 507778, here are decompositions:

59 + 507719 = 507778
137 + 507641 = 507778
179 + 507599 = 507778
281 + 507497 = 507778
317 + 507461 = 507778
347 + 507431 = 507778
419 + 507359 = 507778
431 + 507347 = 507778

Showing the first eight; more decompositions exist.
