Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538602, here are decompositions:

23 + 31538579 = 31538602
41 + 31538561 = 31538602
113 + 31538489 = 31538602
191 + 31538411 = 31538602
269 + 31538333 = 31538602
449 + 31538153 = 31538602
461 + 31538141 = 31538602
569 + 31538033 = 31538602

Showing the first eight; more decompositions exist.
