Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 503642, here are decompositions:

19 + 503623 = 503642
31 + 503611 = 503642
43 + 503599 = 503642
79 + 503563 = 503642
211 + 503431 = 503642
229 + 503413 = 503642
283 + 503359 = 503642
409 + 503233 = 503642

Showing the first eight; more decompositions exist.
