Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504590, here are decompositions:

17 + 31504573 = 31504590
23 + 31504567 = 31504590
43 + 31504547 = 31504590
97 + 31504493 = 31504590
109 + 31504481 = 31504590
137 + 31504453 = 31504590
151 + 31504439 = 31504590
223 + 31504367 = 31504590

Showing the first eight; more decompositions exist.
