Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465718, here are decompositions:

7 + 31465711 = 31465718
139 + 31465579 = 31465718
157 + 31465561 = 31465718
397 + 31465321 = 31465718
409 + 31465309 = 31465718
541 + 31465177 = 31465718
607 + 31465111 = 31465718
619 + 31465099 = 31465718

Showing the first eight; more decompositions exist.
