Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31572634, here are decompositions:

83 + 31572551 = 31572634
101 + 31572533 = 31572634
113 + 31572521 = 31572634
173 + 31572461 = 31572634
263 + 31572371 = 31572634
293 + 31572341 = 31572634
311 + 31572323 = 31572634
491 + 31572143 = 31572634

Showing the first eight; more decompositions exist.
