Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61290, here are decompositions:

7 + 61283 = 61290
29 + 61261 = 61290
37 + 61253 = 61290
59 + 61231 = 61290
67 + 61223 = 61290
79 + 61211 = 61290
137 + 61153 = 61290
139 + 61151 = 61290

Showing the first eight; more decompositions exist.
