Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 161048, here are decompositions:

31 + 161017 = 161048
67 + 160981 = 161048
79 + 160969 = 161048
241 + 160807 = 161048
337 + 160711 = 161048
367 + 160681 = 161048
379 + 160669 = 161048
397 + 160651 = 161048

Showing the first eight; more decompositions exist.
