Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495136, here are decompositions:

19 + 31495117 = 31495136
73 + 31495063 = 31495136
157 + 31494979 = 31495136
193 + 31494943 = 31495136
199 + 31494937 = 31495136
229 + 31494907 = 31495136
367 + 31494769 = 31495136
373 + 31494763 = 31495136

Showing the first eight; more decompositions exist.
