Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461070, here are decompositions:

23 + 31461047 = 31461070
59 + 31461011 = 31461070
191 + 31460879 = 31461070
197 + 31460873 = 31461070
233 + 31460837 = 31461070
239 + 31460831 = 31461070
353 + 31460717 = 31461070
461 + 31460609 = 31461070

Showing the first eight; more decompositions exist.
