Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483954, here are decompositions:

41 + 31483913 = 31483954
71 + 31483883 = 31483954
83 + 31483871 = 31483954
113 + 31483841 = 31483954
263 + 31483691 = 31483954
401 + 31483553 = 31483954
461 + 31483493 = 31483954
521 + 31483433 = 31483954

Showing the first eight; more decompositions exist.
