Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 181052, here are decompositions:

13 + 181039 = 181052
103 + 180949 = 181052
181 + 180871 = 181052
241 + 180811 = 181052
373 + 180679 = 181052
541 + 180511 = 181052
661 + 180391 = 181052
673 + 180379 = 181052

Showing the first eight; more decompositions exist.
