Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31481702, here are decompositions:

19 + 31481683 = 31481702
79 + 31481623 = 31481702
181 + 31481521 = 31481702
193 + 31481509 = 31481702
223 + 31481479 = 31481702
229 + 31481473 = 31481702
271 + 31481431 = 31481702
283 + 31481419 = 31481702

Showing the first eight; more decompositions exist.
