Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538144, here are decompositions:

17 + 538127 = 538144
23 + 538121 = 538144
71 + 538073 = 538144
401 + 537743 = 538144
557 + 537587 = 538144
617 + 537527 = 538144
647 + 537497 = 538144
743 + 537401 = 538144

Showing the first eight; more decompositions exist.
