Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528614, here are decompositions:

41 + 31528573 = 31528614
67 + 31528547 = 31528614
83 + 31528531 = 31528614
113 + 31528501 = 31528614
163 + 31528451 = 31528614
167 + 31528447 = 31528614
181 + 31528433 = 31528614
241 + 31528373 = 31528614

Showing the first eight; more decompositions exist.
