Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610698, here are decompositions:

59 + 31610639 = 31610698
137 + 31610561 = 31610698
179 + 31610519 = 31610698
359 + 31610339 = 31610698
419 + 31610279 = 31610698
461 + 31610237 = 31610698
467 + 31610231 = 31610698
557 + 31610141 = 31610698

Showing the first eight; more decompositions exist.
