Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148590, here are decompositions:

11 + 148579 = 148590
17 + 148573 = 148590
41 + 148549 = 148590
53 + 148537 = 148590
59 + 148531 = 148590
73 + 148517 = 148590
89 + 148501 = 148590
107 + 148483 = 148590

Showing the first eight; more decompositions exist.
