Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101590, here are decompositions:

17 + 101573 = 101590
29 + 101561 = 101590
53 + 101537 = 101590
59 + 101531 = 101590
89 + 101501 = 101590
101 + 101489 = 101590
107 + 101483 = 101590
113 + 101477 = 101590

Showing the first eight; more decompositions exist.
