Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 181054, here are decompositions:

23 + 181031 = 181054
53 + 181001 = 181054
257 + 180797 = 181054
281 + 180773 = 181054
353 + 180701 = 181054
431 + 180623 = 181054
491 + 180563 = 181054
521 + 180533 = 181054

Showing the first eight; more decompositions exist.
