Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513052, here are decompositions:

3 + 31513049 = 31513052
19 + 31513033 = 31513052
61 + 31512991 = 31513052
139 + 31512913 = 31513052
211 + 31512841 = 31513052
229 + 31512823 = 31513052
283 + 31512769 = 31513052
313 + 31512739 = 31513052

Showing the first eight; more decompositions exist.
