Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514770, here are decompositions:

29 + 31514741 = 31514770
83 + 31514687 = 31514770
107 + 31514663 = 31514770
191 + 31514579 = 31514770
197 + 31514573 = 31514770
233 + 31514537 = 31514770
257 + 31514513 = 31514770
293 + 31514477 = 31514770

Showing the first eight; more decompositions exist.
