Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489322, here are decompositions:

43 + 31489279 = 31489322
79 + 31489243 = 31489322
313 + 31489009 = 31489322
331 + 31488991 = 31489322
463 + 31488859 = 31489322
523 + 31488799 = 31489322
691 + 31488631 = 31489322
829 + 31488493 = 31489322

Showing the first eight; more decompositions exist.
