Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61378, here are decompositions:

47 + 61331 = 61378
167 + 61211 = 61378
227 + 61151 = 61378
257 + 61121 = 61378
347 + 61031 = 61378
461 + 60917 = 61378
479 + 60899 = 61378
491 + 60887 = 61378

Showing the first eight; more decompositions exist.
