Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488762, here are decompositions:

29 + 31488733 = 31488762
131 + 31488631 = 31488762
199 + 31488563 = 31488762
269 + 31488493 = 31488762
281 + 31488481 = 31488762
293 + 31488469 = 31488762
433 + 31488329 = 31488762
439 + 31488323 = 31488762

Showing the first eight; more decompositions exist.
