Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101620, here are decompositions:

17 + 101603 = 101620
47 + 101573 = 101620
59 + 101561 = 101620
83 + 101537 = 101620
89 + 101531 = 101620
107 + 101513 = 101620
131 + 101489 = 101620
137 + 101483 = 101620

Showing the first eight; more decompositions exist.
