Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483144, here are decompositions:

47 + 31483097 = 31483144
83 + 31483061 = 31483144
167 + 31482977 = 31483144
197 + 31482947 = 31483144
311 + 31482833 = 31483144
383 + 31482761 = 31483144
401 + 31482743 = 31483144
461 + 31482683 = 31483144

Showing the first eight; more decompositions exist.
