Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459590, here are decompositions:

37 + 31459553 = 31459590
73 + 31459517 = 31459590
103 + 31459487 = 31459590
157 + 31459433 = 31459590
181 + 31459409 = 31459590
191 + 31459399 = 31459590
233 + 31459357 = 31459590
241 + 31459349 = 31459590

Showing the first eight; more decompositions exist.
