Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615714, here are decompositions:

3 + 31615711 = 31615714
131 + 31615583 = 31615714
311 + 31615403 = 31615714
401 + 31615313 = 31615714
503 + 31615211 = 31615714
521 + 31615193 = 31615714
587 + 31615127 = 31615714
617 + 31615097 = 31615714

Showing the first eight; more decompositions exist.
