Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620634, here are decompositions:

53 + 31620581 = 31620634
113 + 31620521 = 31620634
137 + 31620497 = 31620634
191 + 31620443 = 31620634
317 + 31620317 = 31620634
431 + 31620203 = 31620634
443 + 31620191 = 31620634
467 + 31620167 = 31620634

Showing the first eight; more decompositions exist.
