Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61372, here are decompositions:

29 + 61343 = 61372
41 + 61331 = 61372
89 + 61283 = 61372
149 + 61223 = 61372
251 + 61121 = 61372
281 + 61091 = 61372
419 + 60953 = 61372
449 + 60923 = 61372

Showing the first eight; more decompositions exist.
