Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 544642, here are decompositions:

11 + 544631 = 544642
29 + 544613 = 544642
41 + 544601 = 544642
191 + 544451 = 544642
239 + 544403 = 544642
269 + 544373 = 544642
383 + 544259 = 544642
419 + 544223 = 544642

Showing the first eight; more decompositions exist.
