Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611448, here are decompositions:

107 + 31611341 = 31611448
137 + 31611311 = 31611448
149 + 31611299 = 31611448
311 + 31611137 = 31611448
347 + 31611101 = 31611448
359 + 31611089 = 31611448
419 + 31611029 = 31611448
431 + 31611017 = 31611448

Showing the first eight; more decompositions exist.
