Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613500, here are decompositions:

59 + 31613441 = 31613500
89 + 31613411 = 31613500
101 + 31613399 = 31613500
167 + 31613333 = 31613500
251 + 31613249 = 31613500
257 + 31613243 = 31613500
383 + 31613117 = 31613500
509 + 31612991 = 31613500

Showing the first eight; more decompositions exist.
