Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981590, here are decompositions:

3 + 981587 = 981590
13 + 981577 = 981590
67 + 981523 = 981590
73 + 981517 = 981590
97 + 981493 = 981590
109 + 981481 = 981590
139 + 981451 = 981590
151 + 981439 = 981590

Showing the first eight; more decompositions exist.
