Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31447734, here are decompositions:

53 + 31447681 = 31447734
61 + 31447673 = 31447734
67 + 31447667 = 31447734
103 + 31447631 = 31447734
107 + 31447627 = 31447734
127 + 31447607 = 31447734
151 + 31447583 = 31447734
257 + 31447477 = 31447734

Showing the first eight; more decompositions exist.
