Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180650, here are decompositions:

3 + 180647 = 180650
103 + 180547 = 180650
109 + 180541 = 180650
139 + 180511 = 180650
271 + 180379 = 180650
313 + 180337 = 180650
409 + 180241 = 180650
439 + 180211 = 180650

Showing the first eight; more decompositions exist.
