Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548906, here are decompositions:

83 + 31548823 = 31548906
89 + 31548817 = 31548906
139 + 31548767 = 31548906
149 + 31548757 = 31548906
157 + 31548749 = 31548906
163 + 31548743 = 31548906
167 + 31548739 = 31548906
173 + 31548733 = 31548906

Showing the first eight; more decompositions exist.
