Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105590, here are decompositions:

61 + 105529 = 105590
73 + 105517 = 105590
193 + 105397 = 105590
211 + 105379 = 105590
223 + 105367 = 105590
229 + 105361 = 105590
271 + 105319 = 105590
313 + 105277 = 105590

Showing the first eight; more decompositions exist.
