Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488534, here are decompositions:

37 + 31488497 = 31488534
41 + 31488493 = 31488534
53 + 31488481 = 31488534
71 + 31488463 = 31488534
101 + 31488433 = 31488534
127 + 31488407 = 31488534
163 + 31488371 = 31488534
211 + 31488323 = 31488534

Showing the first eight; more decompositions exist.
