Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613992, here are decompositions:

29 + 31613963 = 31613992
131 + 31613861 = 31613992
149 + 31613843 = 31613992
173 + 31613819 = 31613992
191 + 31613801 = 31613992
353 + 31613639 = 31613992
479 + 31613513 = 31613992
593 + 31613399 = 31613992

Showing the first eight; more decompositions exist.
