Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145412, here are decompositions:

13 + 145399 = 145412
31 + 145381 = 145412
109 + 145303 = 145412
193 + 145219 = 145412
199 + 145213 = 145412
349 + 145063 = 145412
439 + 144973 = 145412
523 + 144889 = 145412

Showing the first eight; more decompositions exist.
