Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607590, here are decompositions:

11 + 31607579 = 31607590
59 + 31607531 = 31607590
101 + 31607489 = 31607590
167 + 31607423 = 31607590
191 + 31607399 = 31607590
227 + 31607363 = 31607590
233 + 31607357 = 31607590
263 + 31607327 = 31607590

Showing the first eight; more decompositions exist.
