Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615822, here are decompositions:

59 + 31615763 = 31615822
233 + 31615589 = 31615822
239 + 31615583 = 31615822
383 + 31615439 = 31615822
419 + 31615403 = 31615822
431 + 31615391 = 31615822
479 + 31615343 = 31615822
509 + 31615313 = 31615822

Showing the first eight; more decompositions exist.
