Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614752, here are decompositions:

19 + 31614733 = 31614752
109 + 31614643 = 31614752
151 + 31614601 = 31614752
193 + 31614559 = 31614752
229 + 31614523 = 31614752
409 + 31614343 = 31614752
523 + 31614229 = 31614752
541 + 31614211 = 31614752

Showing the first eight; more decompositions exist.
