Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615184, here are decompositions:

31 + 31615153 = 31615184
241 + 31614943 = 31615184
331 + 31614853 = 31615184
397 + 31614787 = 31615184
487 + 31614697 = 31615184
541 + 31614643 = 31615184
661 + 31614523 = 31615184
691 + 31614493 = 31615184

Showing the first eight; more decompositions exist.
