Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488564, here are decompositions:

7 + 31488557 = 31488564
17 + 31488547 = 31488564
67 + 31488497 = 31488564
71 + 31488493 = 31488564
83 + 31488481 = 31488564
101 + 31488463 = 31488564
131 + 31488433 = 31488564
157 + 31488407 = 31488564

Showing the first eight; more decompositions exist.
