Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488350, here are decompositions:

79 + 31488271 = 31488350
139 + 31488211 = 31488350
241 + 31488109 = 31488350
331 + 31488019 = 31488350
337 + 31488013 = 31488350
373 + 31487977 = 31488350
409 + 31487941 = 31488350
433 + 31487917 = 31488350

Showing the first eight; more decompositions exist.
