Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61330, here are decompositions:

47 + 61283 = 61330
107 + 61223 = 61330
179 + 61151 = 61330
239 + 61091 = 61330
431 + 60899 = 61330
443 + 60887 = 61330
461 + 60869 = 61330
509 + 60821 = 61330

Showing the first eight; more decompositions exist.
