Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 49090, here are decompositions:

47 + 49043 = 49090
53 + 49037 = 49090
59 + 49031 = 49090
71 + 49019 = 49090
101 + 48989 = 49090
137 + 48953 = 49090
233 + 48857 = 49090
269 + 48821 = 49090

Showing the first eight; more decompositions exist.
