Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601450, here are decompositions:

43 + 31601407 = 31601450
103 + 31601347 = 31601450
109 + 31601341 = 31601450
271 + 31601179 = 31601450
313 + 31601137 = 31601450
367 + 31601083 = 31601450
373 + 31601077 = 31601450
409 + 31601041 = 31601450

Showing the first eight; more decompositions exist.
