Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613548, here are decompositions:

107 + 31613441 = 31613548
137 + 31613411 = 31613548
149 + 31613399 = 31613548
191 + 31613357 = 31613548
257 + 31613291 = 31613548
431 + 31613117 = 31613548
521 + 31613027 = 31613548
557 + 31612991 = 31613548

Showing the first eight; more decompositions exist.
