Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527782, here are decompositions:

73 + 31527709 = 31527782
79 + 31527703 = 31527782
199 + 31527583 = 31527782
241 + 31527541 = 31527782
283 + 31527499 = 31527782
439 + 31527343 = 31527782
571 + 31527211 = 31527782
631 + 31527151 = 31527782

Showing the first eight; more decompositions exist.
