Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537132, here are decompositions:

5 + 31537127 = 31537132
83 + 31537049 = 31537132
89 + 31537043 = 31537132
131 + 31537001 = 31537132
149 + 31536983 = 31537132
173 + 31536959 = 31537132
269 + 31536863 = 31537132
311 + 31536821 = 31537132

Showing the first eight; more decompositions exist.
