Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548148, here are decompositions:

101 + 31548047 = 31548148
131 + 31548017 = 31548148
167 + 31547981 = 31548148
227 + 31547921 = 31548148
311 + 31547837 = 31548148
557 + 31547591 = 31548148
617 + 31547531 = 31548148
641 + 31547507 = 31548148

Showing the first eight; more decompositions exist.
