Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618594, here are decompositions:

47 + 31618547 = 31618594
131 + 31618463 = 31618594
191 + 31618403 = 31618594
233 + 31618361 = 31618594
383 + 31618211 = 31618594
401 + 31618193 = 31618594
431 + 31618163 = 31618594
461 + 31618133 = 31618594

Showing the first eight; more decompositions exist.
