Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601184, here are decompositions:

5 + 31601179 = 31601184
47 + 31601137 = 31601184
101 + 31601083 = 31601184
107 + 31601077 = 31601184
191 + 31600993 = 31601184
227 + 31600957 = 31601184
367 + 31600817 = 31601184
383 + 31600801 = 31601184

Showing the first eight; more decompositions exist.
