Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547832, here are decompositions:

83 + 31547749 = 31547832
101 + 31547731 = 31547832
131 + 31547701 = 31547832
139 + 31547693 = 31547832
149 + 31547683 = 31547832
191 + 31547641 = 31547832
223 + 31547609 = 31547832
241 + 31547591 = 31547832

Showing the first eight; more decompositions exist.
