Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577526, here are decompositions:

5 + 31577521 = 31577526
17 + 31577509 = 31577526
53 + 31577473 = 31577526
109 + 31577417 = 31577526
137 + 31577389 = 31577526
139 + 31577387 = 31577526
157 + 31577369 = 31577526
163 + 31577363 = 31577526

Showing the first eight; more decompositions exist.
