Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615624, here are decompositions:

41 + 31615583 = 31615624
233 + 31615391 = 31615624
281 + 31615343 = 31615624
311 + 31615313 = 31615624
431 + 31615193 = 31615624
461 + 31615163 = 31615624
563 + 31615061 = 31615624
617 + 31615007 = 31615624

Showing the first eight; more decompositions exist.
