Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562758, here are decompositions:

47 + 31562711 = 31562758
131 + 31562627 = 31562758
137 + 31562621 = 31562758
191 + 31562567 = 31562758
239 + 31562519 = 31562758
257 + 31562501 = 31562758
317 + 31562441 = 31562758
401 + 31562357 = 31562758

Showing the first eight; more decompositions exist.
