Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483972, here are decompositions:

53 + 31483919 = 31483972
59 + 31483913 = 31483972
83 + 31483889 = 31483972
89 + 31483883 = 31483972
101 + 31483871 = 31483972
131 + 31483841 = 31483972
173 + 31483799 = 31483972
239 + 31483733 = 31483972

Showing the first eight; more decompositions exist.
