Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488504, here are decompositions:

7 + 31488497 = 31488504
11 + 31488493 = 31488504
23 + 31488481 = 31488504
41 + 31488463 = 31488504
71 + 31488433 = 31488504
97 + 31488407 = 31488504
181 + 31488323 = 31488504
211 + 31488293 = 31488504

Showing the first eight; more decompositions exist.
