Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513262, here are decompositions:

3 + 31513259 = 31513262
43 + 31513219 = 31513262
61 + 31513201 = 31513262
139 + 31513123 = 31513262
199 + 31513063 = 31513262
229 + 31513033 = 31513262
271 + 31512991 = 31513262
349 + 31512913 = 31513262

Showing the first eight; more decompositions exist.
