Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613784, here are decompositions:

67 + 31613717 = 31613784
157 + 31613627 = 31613784
233 + 31613551 = 31613784
271 + 31613513 = 31613784
347 + 31613437 = 31613784
373 + 31613411 = 31613784
383 + 31613401 = 31613784
401 + 31613383 = 31613784

Showing the first eight; more decompositions exist.
