Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601472, here are decompositions:

61 + 31601411 = 31601472
79 + 31601393 = 31601472
113 + 31601359 = 31601472
131 + 31601341 = 31601472
269 + 31601203 = 31601472
281 + 31601191 = 31601472
293 + 31601179 = 31601472
373 + 31601099 = 31601472

Showing the first eight; more decompositions exist.
