Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488654, here are decompositions:

7 + 31488647 = 31488654
23 + 31488631 = 31488654
97 + 31488557 = 31488654
107 + 31488547 = 31488654
157 + 31488497 = 31488654
173 + 31488481 = 31488654
191 + 31488463 = 31488654
283 + 31488371 = 31488654

Showing the first eight; more decompositions exist.
