Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537262, here are decompositions:

19 + 31537243 = 31537262
61 + 31537201 = 31537262
109 + 31537153 = 31537262
223 + 31537039 = 31537262
271 + 31536991 = 31537262
433 + 31536829 = 31537262
439 + 31536823 = 31537262
733 + 31536529 = 31537262

Showing the first eight; more decompositions exist.
