Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601442, here are decompositions:

31 + 31601411 = 31601442
83 + 31601359 = 31601442
101 + 31601341 = 31601442
179 + 31601263 = 31601442
239 + 31601203 = 31601442
251 + 31601191 = 31601442
263 + 31601179 = 31601442
359 + 31601083 = 31601442

Showing the first eight; more decompositions exist.
