Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452862, here are decompositions:

3 + 31452859 = 31452862
11 + 31452851 = 31452862
59 + 31452803 = 31452862
113 + 31452749 = 31452862
131 + 31452731 = 31452862
179 + 31452683 = 31452862
239 + 31452623 = 31452862
263 + 31452599 = 31452862

Showing the first eight; more decompositions exist.
