Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527578, here are decompositions:

37 + 31527541 = 31527578
79 + 31527499 = 31527578
97 + 31527481 = 31527578
331 + 31527247 = 31527578
367 + 31527211 = 31527578
421 + 31527157 = 31527578
769 + 31526809 = 31527578
787 + 31526791 = 31527578

Showing the first eight; more decompositions exist.
