Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61972, here are decompositions:

5 + 61967 = 61972
11 + 61961 = 61972
23 + 61949 = 61972
101 + 61871 = 61972
191 + 61781 = 61972
269 + 61703 = 61972
359 + 61613 = 61972
389 + 61583 = 61972

Showing the first eight; more decompositions exist.
