Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485702, here are decompositions:

41 + 31485661 = 31485702
103 + 31485599 = 31485702
229 + 31485473 = 31485702
271 + 31485431 = 31485702
349 + 31485353 = 31485702
383 + 31485319 = 31485702
389 + 31485313 = 31485702
401 + 31485301 = 31485702

Showing the first eight; more decompositions exist.
