Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180426, here are decompositions:

7 + 180419 = 180426
13 + 180413 = 180426
47 + 180379 = 180426
79 + 180347 = 180426
89 + 180337 = 180426
109 + 180317 = 180426
137 + 180289 = 180426
139 + 180287 = 180426

Showing the first eight; more decompositions exist.
