Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614780, here are decompositions:

11 + 31614769 = 31614780
47 + 31614733 = 31614780
73 + 31614707 = 31614780
79 + 31614701 = 31614780
83 + 31614697 = 31614780
103 + 31614677 = 31614780
137 + 31614643 = 31614780
139 + 31614641 = 31614780

Showing the first eight; more decompositions exist.
