Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 544438, here are decompositions:

71 + 544367 = 544438
179 + 544259 = 544438
239 + 544199 = 544438
431 + 544007 = 544438
467 + 543971 = 544438
509 + 543929 = 544438
641 + 543797 = 544438
647 + 543791 = 544438

Showing the first eight; more decompositions exist.
