Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514370, here are decompositions:

61 + 31514309 = 31514370
73 + 31514297 = 31514370
79 + 31514291 = 31514370
103 + 31514267 = 31514370
109 + 31514261 = 31514370
131 + 31514239 = 31514370
149 + 31514221 = 31514370
179 + 31514191 = 31514370

Showing the first eight; more decompositions exist.
