Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19046, here are decompositions:

37 + 19009 = 19046
67 + 18979 = 19046
73 + 18973 = 19046
127 + 18919 = 19046
367 + 18679 = 19046
409 + 18637 = 19046
463 + 18583 = 19046
523 + 18523 = 19046

Showing the first eight; more decompositions exist.
