Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539734, here are decompositions:

7 + 31539727 = 31539734
73 + 31539661 = 31539734
151 + 31539583 = 31539734
211 + 31539523 = 31539734
313 + 31539421 = 31539734
367 + 31539367 = 31539734
397 + 31539337 = 31539734
463 + 31539271 = 31539734

Showing the first eight; more decompositions exist.
