Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938144, here are decompositions:

37 + 938107 = 938144
61 + 938083 = 938144
73 + 938071 = 938144
127 + 938017 = 938144
241 + 937903 = 938144
331 + 937813 = 938144
367 + 937777 = 938144
397 + 937747 = 938144

Showing the first eight; more decompositions exist.
