Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484144, here are decompositions:

73 + 31484071 = 31484144
163 + 31483981 = 31484144
283 + 31483861 = 31484144
337 + 31483807 = 31484144
421 + 31483723 = 31484144
547 + 31483597 = 31484144
673 + 31483471 = 31484144
691 + 31483453 = 31484144

Showing the first eight; more decompositions exist.
