Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497584, here are decompositions:

7 + 31497577 = 31497584
37 + 31497547 = 31497584
43 + 31497541 = 31497584
61 + 31497523 = 31497584
193 + 31497391 = 31497584
271 + 31497313 = 31497584
397 + 31497187 = 31497584
457 + 31497127 = 31497584

Showing the first eight; more decompositions exist.
