Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620754, here are decompositions:

3 + 31620751 = 31620754
5 + 31620749 = 31620754
17 + 31620737 = 31620754
71 + 31620683 = 31620754
173 + 31620581 = 31620754
233 + 31620521 = 31620754
257 + 31620497 = 31620754
281 + 31620473 = 31620754

Showing the first eight; more decompositions exist.
