Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137090, here are decompositions:

3 + 137087 = 137090
13 + 137077 = 137090
61 + 137029 = 137090
97 + 136993 = 137090
103 + 136987 = 137090
127 + 136963 = 137090
139 + 136951 = 137090
193 + 136897 = 137090

Showing the first eight; more decompositions exist.
