Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462722, here are decompositions:

73 + 31462649 = 31462722
113 + 31462609 = 31462722
131 + 31462591 = 31462722
139 + 31462583 = 31462722
149 + 31462573 = 31462722
191 + 31462531 = 31462722
241 + 31462481 = 31462722
251 + 31462471 = 31462722

Showing the first eight; more decompositions exist.
