Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590994, here are decompositions:

3 + 31590991 = 31590994
53 + 31590941 = 31590994
101 + 31590893 = 31590994
107 + 31590887 = 31590994
191 + 31590803 = 31590994
257 + 31590737 = 31590994
263 + 31590731 = 31590994
311 + 31590683 = 31590994

Showing the first eight; more decompositions exist.
