Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573584, here are decompositions:

13 + 31573571 = 31573584
23 + 31573561 = 31573584
61 + 31573523 = 31573584
71 + 31573513 = 31573584
83 + 31573501 = 31573584
157 + 31573427 = 31573584
191 + 31573393 = 31573584
193 + 31573391 = 31573584

Showing the first eight; more decompositions exist.
