Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465444, here are decompositions:

53 + 31465391 = 31465444
251 + 31465193 = 31465444
383 + 31465061 = 31465444
503 + 31464941 = 31465444
617 + 31464827 = 31465444
743 + 31464701 = 31465444
827 + 31464617 = 31465444
863 + 31464581 = 31465444

Showing the first eight; more decompositions exist.
