Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467590, here are decompositions:

3 + 31467587 = 31467590
19 + 31467571 = 31467590
31 + 31467559 = 31467590
109 + 31467481 = 31467590
157 + 31467433 = 31467590
223 + 31467367 = 31467590
331 + 31467259 = 31467590
409 + 31467181 = 31467590

Showing the first eight; more decompositions exist.
