Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469444, here are decompositions:

3 + 31469441 = 31469444
37 + 31469407 = 31469444
151 + 31469293 = 31469444
157 + 31469287 = 31469444
313 + 31469131 = 31469444
541 + 31468903 = 31469444
991 + 31468453 = 31469444
997 + 31468447 = 31469444

Showing the first eight; more decompositions exist.
