Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527626, here are decompositions:

43 + 31527583 = 31527626
103 + 31527523 = 31527626
127 + 31527499 = 31527626
283 + 31527343 = 31527626
349 + 31527277 = 31527626
373 + 31527253 = 31527626
379 + 31527247 = 31527626
433 + 31527193 = 31527626

Showing the first eight; more decompositions exist.
