Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499084, here are decompositions:

7 + 31499077 = 31499084
61 + 31499023 = 31499084
271 + 31498813 = 31499084
571 + 31498513 = 31499084
613 + 31498471 = 31499084
811 + 31498273 = 31499084
997 + 31498087 = 31499084
1087 + 31497997 = 31499084

Showing the first eight; more decompositions exist.
