Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180434, here are decompositions:

43 + 180391 = 180434
73 + 180361 = 180434
97 + 180337 = 180434
103 + 180331 = 180434
127 + 180307 = 180434
193 + 180241 = 180434
223 + 180211 = 180434
337 + 180097 = 180434

Showing the first eight; more decompositions exist.
